The code internal to the recursive merge strategy was not fully
prepared to see a path that is renamed to try overwriting another
path that is only different in case on case insensitive systems.
This does not matter in the current code, but will start to matter
once the rename detection logic starts taking hints from nearby
paths moving to some directory and moves a new path along with them.

branch: update warning message shown when copying a misnamed branch
When a user tries to rename a branch that has a "bad name" (e.g.,
starts with a '-') then we warn them that the misnamed branch has
been renamed "away". A similar message is shown when trying to create
a copy of a misnamed branch even though it doesn't remove the misnamed
branch. This is not correct and may confuse the user.
So, update the warning message shown to be more precise that only a copy
of the misnamed branch has been created. It's better to show the warning
message than not showing it at all as it makes the user aware of the
presence of a misnamed branch.

git-clone and git-checkout both invoke the post-checkout hook following
a successful checkout, yet git-worktree neglects to do so even though it
too "checks out" the worktree. Fix this oversight.
Implementation note: The newly-created worktree may reference a branch
or be detached. In the latter case, a commit lookup is performed, though
the result is used only in a boolean sense to (a) determine if the
commit actually exists, and (b) assign either the branch name or commit
ID to HEAD. Since the post-commit hook needs to know the ID of the
checked-out commit, the lookup now needs to be done in all cases, rather
than only when detached. Consequently, a new boolean is needed to handle
(b) since the lookup result itself can no longer perform that role.

If other strbuf add functions cause the first allocation and
subsequently encounter an error then they release the memory, restoring

launch_editor(): indicate that Git waits for user input
When a graphical GIT_EDITOR is spawned by a Git command that opens
and waits for user input (e.g. "git rebase -i"), then the editor window
might be obscured by other windows. The user might be left staring at
the original Git terminal window without even realizing that s/he needs
to interact with another window before Git can proceed. To this user Git
appears hanging.
Print a message that Git is waiting for editor input in the original
terminal and get rid of it when the editor returns, if the terminal
supports erasing the last line. Also, make sure that our message is
terminated with a whitespace so that any message the editor may show
upon starting up will be kept separate from our message.
Power users might not want to see this message or their editor might
already print such a message (e.g. emacsclient). Allow these users to
suppress the message by disabling the "advice.waitingForEditor" config.
The standard advise() function is not used here as it would always add
a newline which would make deleting the message harder.

diff-tree: read the index so attribute checks work in bare repositories
A regression was introduced in 557a5998d (submodule: remove
gitmodules_config, 2017-08-03) to how attribute processing was handled
in bare repositories when running the diff-tree command.
By default the attribute system will first try to read ".gitattribute"
files from the working tree and then falls back to reading them from the
index if there isn't a copy checked out in the worktree. Prior to 557a5998d the index was read as a side effect of the call to
'gitmodules_config()' which ensured that the index was already populated
before entering the attribute subsystem.
Since the call to 'gitmodules_config()' was removed the index is no
longer being read so when the attribute system tries to read from the
in-memory index it doesn't find any ".gitattribute" entries effectively
ignoring any configured attributes.
Fix this by explicitly reading the index during the setup of diff-tree.

worktree: add --guess-remote flag to add subcommand
Currently 'git worktree add <path>' creates a new branch named after the

It's sometimes useful to have 'git worktree add <path> behave more like
the dwim machinery in 'git checkout <new-branch>', i.e. check if the new
branch name, derived from the basename of the <path>, uniquely matches
the branch name of a remote-tracking branch, and if so check out that
branch and set the upstream to the remote-tracking branch.

Internaly we use 0{40} as a placeholder object name to signal the

it anew" by passing 0{40} for the 'old' side), and expect that a

Because our test suite is not about validating the working of the
shell, it is pointless to test variations of how a literal string
'yes' is quoted when assigned to an environment variable.
Instead, test various ways to spell 'yes' (we use strcasecmp() so
uppercased and capitalized variant should work just like 'yes'
spelled in all lowercase) and make sure we take them as 'yes'. That
is more relevant in testing Git.

t4013: prepare for upcoming "diff --raw --abbrev" output format change
Most of the t4013 tests go through a list of sample command lines,
and each of them is executed and its output compared with an
expected one stored in t4013/ directory. Allow these lines to begin
with a colon followed by magic word(s) so that test conditions can
easily be tweaked.
The expected use that will happen in later steps of this is to run
tests expecting the traditional output and run the same test without
the GIT_PRINT_SHA1_ELLIPSIS=yes environment exported for (perhaps
some of) them, which will have to expect different output. Since
all of the existing tests are meant to run with the environment,
use the magic word "noellipses" to cause the variable not to be set
and exported.
As this step does not add any new test with the magic word, all
tests still run with the environment variable, expecting the
traditional output, but it will change soon.
