wt-status: fix possible use of uninitialized variable
In wt_status_print_change_data, we accept a change_type flag
that is meant to be either WT_STATUS_UPDATED or
WT_STATUS_CHANGED. We then switch() on this value to set
the local variable "status" for each case, but do not
provide a fallback "default" label to the switch statement.
As a result, the compiler realizes that "status" might be
unset, and complains with a warning. To silence this
warning, we use the "int status = status" trick. This is
correct with the current code, as all callers provide one of
the two expected change_type flags. However, it's also a
maintenance trap, as there is nothing to prevent future
callers from passing another flag, nor to document this
assumption.
Instead of using the "x = x" hack, let's handle the default
case in the switch() statement with a die("BUG"). That tells
the compiler and any readers of the code exactly what the
function's input assumptions are.
We could also convert the flag to an enum, which would
provide a compile-time check on the function input. However,
since these flags are part of a larger enum, that would make
the code unnecessarily complex (we would have to make a new
enum with just the two flags, and then convert it to the old
enum for passing to sub-functions).

fast-import: clarify "inline" logic in file_change_m
When we read a fast-import line like:
M 100644 :1 foo.c
we point the local object_entry variable "oe" to the object
named by the mark ":1". When the input uses the "inline"
construct, however, we do not have such an object_entry.
The current code is careful not to access "oe" in the inline
case, but we can make the assumption even more obvious (and
catch violations of it) by setting oe to NULL and adding a
comment. As a bonus, this also squelches an over-zealous gcc
-Wuninitialized warning, which means we can drop the "oe =
oe" initialization hack.

run-command: always set failed_errno in start_command
When we fail to fork, we set the failed_errno variable to
the value of errno so it is not clobbered by later syscalls.
However, we do so in a conditional, and it is hard to see
later under what conditions the variable has a valid value.
Instead of setting it only when fork fails, let's just
always set it after forking. This is more obvious for human
readers (as we are no longer setting it as a side effect of
a strerror call), and it is more obvious to gcc, which no
longer generates a spurious -Wuninitialized warning. It also
happens to match what the WIN32 half of the #ifdef does.

According to 47ec794, this initialization is meant to
squelch an erroneous uninitialized variable warning from gcc
4.0.1. That version is quite old at this point, and gcc 4.1
and up handle it fine, with one exception. There seems to be
a regression in gcc 4.6.3, which produces the warning;
however, gcc versions 4.4.7 and 4.7.2 do not.

In cases where the setting and access of a variable are
protected by the same conditional flag, older versions of
gcc would generate a "might be used unitialized" warning. We
silence the warning by initializing the variable to itself,
a hack that gcc recognizes.
Modern versions of gcc are smart enough to get this right,
going back to at least version 4.3.5. gcc 4.1 does get it
wrong in both cases, but is sufficiently old that we
probably don't need to care about it anymore.

git-completion.bash: zsh does not implement function redirection correctly
A recent change added functions whose entire standard error stream
is redirected to /dev/null using a construct that is valid POSIX.1
but is not widely used:
funcname () {
cd "$1" && run some command "$2"
} 2>/dev/null
Even though this file is "git-completion.bash", zsh completion
support dot-sources it (instead of asking bash to grok it like tcsh
completion does), and zsh does not implement this redirection
correctly.
With zsh, trying to complete an inexistant directory gave this:
git add no-such-dir/__git_ls_files_helper:cd:2: no such file or directory: no-such-dir/
Also these functions use "cd" to first go somewhere else before
running a command, but the location the caller wants them to go that
is given as an argument to them should not be affected by CDPATH
variable the users may have set for their interactive session.
To fix both of these, wrap the body of the function in a subshell,
unset CDPATH at the beginning of the subshell, and redirect the
standard error stream of the subshell to /dev/null.

shell: new no-interactive-login command to print a custom message
If I disable git-shell's interactive mode by removing the
~/git-shell-commands directory, attempts to ssh in to the service
produce a message intended for the administrator:
$ ssh git@myserver
fatal: Interactive git shell is not enabled.
hint: ~/git-shell-commands should exist and have read and execute access.
$
That is helpful for the new admin who is wondering "What? Why isn't
the git-shell I just set up working?", but once the site setup is
complete, it would be better to give the user a friendly hint that she
is on the right track, like GitHub does.
Hi <username>! You've successfully authenticated, but
GitHub does not provide shell access.
An appropriate greeting might even include more complex dynamic
information, like gitolite's list of repositories the user has access
to. Add support for a ~/git-shell-commands/no-interactive-login
command that generates an arbitrary greeting. When the user tries to
log in:
* If the file ~/git-shell-commands/no-interactive-login exists,
run no-interactive-login to let the server say what it likes,
then hang up.
* Otherwise, if ~/git-shell-commands/ is present, start an
interactive read-eval-print loop.
* Otherwise, print the usual configuration hint and hang up.

- DESCRIPTION, which gives an overview of the purpose and guarantees

Split the backward-compatibility notes into two sections, the ones
that affect this release, and the other to describe changes meant
for Git 2.0. The latter gives a context to understand why the
changes for this release is necessary.
Documentation/git-push: clarify the description of defaults
We describe what gets pushed by default when the command line does
not give any <refspec> under the bullet point of <refspec>.
It is a bit unfriendly to expect users to read on <refspec> when
they are not giving any in the first place. "What gets pushed" is
determined by taking many factors (<refspec> argument being only one
of them) into account, and is a property of the entire command, not
an individual argument. Also we do not describe "Where the push
goes" when the command line does not say.
Give the description on "what gets pushed to where" upfront before
explaining individual arguments and options.
Also update the description of <refspec> to say what it is, what it
is used for, before explaining what shape it takes.
Currently this is cosmetic change - the merges are ignored, becuase the methods
(lookup_svn_merge, find_rev_before, find_rev_after) are failing on comparing text with number.
See http://www.open.collab.net/community/subversion/articles/merge-info.html
Extract:
The range r30430:30435 that was added to 1.5.x in this merge has a '*' suffix for 1.5.x\www.
This '*' is the marker for a non-inheritable mergeinfo range.

bundle: Fix "verify" output if history is complete
A more informative message for "complete" bundles was added in commit 8c3710fd3011 (tweak "bundle verify" of a complete history, 2012-06-04).
However, the prerequisites ref list is currently read *after* we
check if it equals zero, which means we never actually use the
