This is because 'git rev-parse --revs-only --no-flags "$@"' always
"exit 0" and outputs all the SHA1 it can found from parsing "$@".

same logic as for the "bisect bad" argument.

While at it, this patch teaches "bisect bad" to give a meaningfull
error message when it is passed more than one argument.

Note that if "git bisect good" or "git bisect skip" is given some

Fix "git apply" to correctly enforce "match at the beginning"

An earlier commit 4be6096 (apply --unidiff-zero: loosen sanity checks for
--unidiff=0 patches, 2006-09-17) made match_beginning and match_end

recorded at the hunk is line 0, and if a hunk changes at the beginning, it
is line 1.  The new test added to t4104 exposes that the old code did not
insist on matching at the beginning for a patch to add a line to an empty
file.

An even older 65aadb9 (apply: force matching at the beginning.,
2006-05-24) was equally wrong in that it tried to take hints from the
number of leading context lines, to decide if the hunk must match at the
beginning, but we can just look at the line number in the hunk to decide.

gitk: Fix changing colors through Edit->Preferences

With tcl/tk8.5 the lset command seems to behave differently.  When
changing the background color through Edit->Preferences, the changes
are applied, but new dialogs, such as View->New view... barf with

 Error: unknown color name "{#ffffff}"

Additionally when closing gitk, and starting it up again, a bad value
has been saved to ~/.gitk, preventing gitk from running properly; it
fails with

 Error in startup script: unknown color name "{#ffffff}"
 ...

This commit fixes the problem by changing the color dialogs to pass
the empty string {} as the list index to choosecolor.  This causes
the lset and lindex commands used by choosecolor to use and set the
whole variable (bgcolor, fgcolor or selectbgcolor) rather than
treating them as a 1-element list.  Tested with tcl/tk8.4 and 8.5.

 (1) It may be a directory, but it may not be a submodule, and in the
     latter case, the change we need to report is "the blob at the path
     has disappeared".  We need to check with resolve_gitlink_ref() to be
     consistent with what "git add" and "git update-index --add" does.

 (2) lstat(2) may have succeeded only because a leading component of the
     path was turned into a symbolic link that points at something that
     exists in the work tree.  In such a case, the path itself does not

git-p4s handling of Windows style EOL was broken after the removal
of the p4 submit template handling in commit f2a6059. Fix that, and
make getP4OpenedType() more robust.

gitweb: fallback to system-wide config file if default config does not exist

From a distribution point of view, configuration files for applications
should reside in /etc/.  On the other hand it's convenient for multiple
instances of gitweb (e.g. virtual web servers on a single machine) to have
a per-instance configuration file, just as gitweb currently supports
through the file gitweb_config.perl next to the cgi.

To support both at runtime, this commit introduces GITWEB_CONFIG_SYSTEM as
a system-wide configuration file which will be used as a fallback if the
config file sprecified throug GITWEB_CONFIG does not exist.

When a path is examined in the patch subcommand, any mode changes in

are staged, then we throw out that header and do not touch the
path.  But if _any_ hunks are staged, we use the header, and the mode
is changed together with the contents.

Since the 'p'atch command should just be dealing with hunks that are
shown to the user, it makes sense to just ignore mode changes
entirely. We do squirrel away the mode, though, since the next patch
will allow users to select the mode update separately.
