When the whitespace rule tab-in-indent is enabled, apply --whitespace=fix
replaces tabs by the appropriate amount of blanks. The code used
"dst->len % 8" as the criterion to stop adding blanks. But it forgot that
dst holds more than just the current line. Consequently, the modulus was
computed correctly only for the first added line, but not for the second
and subsequent lines. Fix it.

whitespace: we cannot "catch all errors known to git" anymore
Traditionally, "*.txt whitespace" in .gitattributes file has been an
instruction to catch _all_ classes of whitespace errors known to git.
This has to change, however, in order to introduce "tab-in-indent" which
is inherently incompatible with "indent-with-non-tab". As we do not want
to break configuration of existing users, add a mechanism to allow marking

GNU make’s target-specific variables facility has one weird facet: any
variables set for a given target apply to all of its dependencies,
too. For example, when running “make exec_cmd.o”, since exec_cmd.o
depends on GIT-CFLAGS, the variable assignment in
applies when refreshing GIT-CFLAGS, and the extra options get included
in the tracked compiler flags. If an object file like this is the
first target built, GIT-CFLAGS will appear to be out of date,
resulting in useless rebuilds and the dreaded “new build flags or
prefix” message.
This does not happen with every build because GIT-CFLAGS is only
refreshed once in a given “make” run, and usually the first target
does not set any variables. When this problem does rear its head, it
is very annoying.
So put target-specific flags in a separate EXTRA_CPPFLAGS variable
that is not included in $(TRACK_CFLAGS).

refs: ref entry with NULL sha1 is can be a dangling symref
Brandon Casey noticed that t5505 had accidentally broken its && chain,
hiding inconsistency between the code that writes the warning to the
standard output and the test that expects to see the warning on the
standard error, which was introduced by f8948e2 (remote prune: warn
dangling symrefs, 2009-02-08).
It turns out that the issue is deeper than that. After f8948e2, a symref
that is dangling is marked with a NULL sha1, and the idea of using NULL
sha1 to mean a deleted ref was scrapped, but somehow a follow-up eafb452
(do_one_ref(): null_sha1 check is not about broken ref, 2009-07-22)
incorrectly reorganized do_one_ref(), still thinking NULL sha1 is never
used in the code.
Fix this by:
- adopt Brandon's fix to t5505 test;
- introduce REF_BROKEN flag to mark a ref that fails to resolve (dangling
symref);
- move the check for broken ref back inside the "if we are skipping
dangling refs" code block.
Asciidoc takes the first non-space character in the first line of the
paragraph as a reference point for preformatted layout, so adjust to
that to make the table align.

As we walk the directory tree, if we see an ignored path, we
want to add it to the ignored list only if it matches any
pathspec that we were given. We used to check for the
pathspec to appear explicitly. E.g., if we see "subdir/file"
and it is excluded, we check to see if we have "subdir/file"
in our pathspec.
However, this interacts badly with the optimization to avoid
recursing into ignored subdirectories. If "subdir" as a
whole is ignored, then we never recurse, and consider only
whether "subdir" itself is in our pathspec. It would not
match a pathspec of "subdir/file" explicitly, even though it
is the reason that subdir/file would be excluded.
This manifests itself to the user as "git add subdir/file"
failing to correctly note that the pathspec was ignored.
This patch extends the in_pathspec logic to include prefix
directory case.

The test is to prepare an empty file "camelcase" in the index, remove

However, the test actually checked ls-files knows about a pathname that

git status: ignoring untracked files must apply to submodules too
Since 1.7.0 submodules are considered dirty when they contain untracked

too. To achieve this, the new flag DIFF_OPT_IGNORE_UNTRACKED_IN_SUBMODULES

for_each_recent_reflog_ent() to use strbuf_getwholeline() instead of fgets(),
for safety and to avoid any size limits for reflog entries.
Also reverse the logic of the part of the function that only looks at file
tails. It used to close the file if fgets() succeeded. The following
fgets() call in the while loop was likely to fail in this case, too, so
passing an offset to for_each_recent_reflog_ent() never worked. Change it to

git status: Fix false positive "new commits" output for dirty submodules
Testing if the output "new commits" should appear in the long format of
"git status" is done by comparing the hashes of the diffpair. This always
resulted in printing "new commits" for submodules that contained untracked
or modified content, even if they did not contain new commits. The reason
was that match_stat_with_submodule() did set the "changed" flag for dirty
submodules, resulting in two->sha1 being set to the null_sha1 at the call
sites, which indicates that new commits are present. This is changed so
that when no new commits are present, the same object names are in the
sha1 field for both sides of the filepair, and the working tree side will
have the "dirty_submodule" flag set when appropriate. For a submodule to
be seen as modified even when it just has a dirty work tree, some
conditions had to be extended to also check for the "dirty_submodule"
flag.
Unfortunately the test case that should have found this bug had been
changed incorrectly too. It is fixed and extended to test for other
combinations too.

Running 'git notes copy -h' is not very helfpul right now. It lists
the options for all the git notes subcommands and is rather confusing.
Fix this by splitting cmd_notes() into separate functions for each
subcommand (besides append and edit since they're very similar) and
only providing a usage message for the subcommand.
This has an added benefit of reducing the code complexity while making
it safer and easier to read. The downside is we get some code bloat
from similar setup and teardown needed for notes and options parsing.
We also get a bit stricter in options parsing by only allowing
the ref option to come before the subcommand.

already puts this information in $dotest/current, and we just
introduce a similar file for git-am.
