commit: -F overrides -t
Commit dbd0f5c7 (Files given on the command line are relative to $cwd,
2008-08-06) introduced parse_options_fix_filename() as a quick fix for
filename arguments used in the parse options API.
git-commit was still broken. This means
git commit -F log -t temp
in a subdirectory would make git think the log message should be taken
from temp instead of log.
This is because parse_options_fix_filename() calls prefix_filename()
which uses a single static char buffer to do its work. Making two calls
with two char pointers causes the pointers to alias. To prevent
aliasing, we duplicate the string returned by
parse_options_fix_filename().

gitweb: Sanitize title attribute in format_subject_html
Replace control characters with question mark '?' (like in
chop_and_esc_str).
A little background: some web browsers turn on strict (and
unforgiving) XML validating mode for XHTML documents served using
application/xhtml+xml content type. This means among others that
control characters are forbidden to appear in gitweb output.
CGI.pm does by default slight escaping (using simple_escape subroutine
from CGI::Util) of all _attribute_ values (depending on the value of
autoEscape, by default on). This escaping, at least in CGI.pm version
3.10 (most current version at CPAN is 3.43), is minimal: only '"',
'&', '<' and '>' are escaped using named HTML entity references
(", &, < and > respectively). But simple_escape does
not do escaping of control characters such as ^X which are invalid in
XHTML (in strict mode).
If by some accident commit message do contain some control character
in first 50 characters (more or less) of first line of commit message,
and this line is longer than 50 characters (so gitweb shortens it for
display), then gitweb would put this control character in title
attribute (and CGI.pm would not remove them). The tag _contents_ is
safe because it is escaped using esc_html() explicitly, and it
replaces control characters by their printable representation.
While at it: chop_and_escape_str doesn't need capturing group.

dir.c: clean up handling of 'path' parameter in read_directory_recursive()
Right now we pass two different pathnames ('path' and 'base') down to
read_directory_recursive(), and the only real reason for that is that we
want to allow an empty 'base' parameter, but when we do so, we need the
pathname to "opendir()" to be "." rather than the empty string.
And rather than handle that confusion in the caller, we can just fix
read_directory_recursive() to handle the case of an empty path itself,
by just passing opendir() a "." ourselves if the path is empty.
This would allow us to then drop one of the pathnames entirely from the
calling convention, but rather than do that, we'll start separating them
out as a "filesystem pathname" (the one we use for filesystem accesses)
and a "git internal base name" (which is the name that we use for git
internally).
That will eventually allow us to do things like handle different
encodings (eg the filesystem pathnames might be Latin1, while git itself
would use UTF-8 for filename information).

646:JP (JIS X 0201) but they essentially are the same character set and
are used interchangeably. Similarly the set ESC $ @ switches to (JIS X
0208-1978) and ESC $ B switches to (JIS X 0208-1983) are in practice used
interchangeably.
Depending on the iconv library and the locale definition on the system, a
program that converts from another encoding to ISO-2022-JP can produce
different byte sequence, and GIT_TEST_CMP (aka "diff -u") will report the
difference as a failure.
Fix this by converting the expected and the actual output to UTF-8 before
comparing when the end result is ISO-2022-JP. The test vector string in
t3900/ISO-2022-JP.txt is expressed with ASCII and JIS X 0208-1983, but it
can be expressed with any other possible variant, and when converted back
to UTF-8, these variants produce identical byte sequences.

gitweb: Use block form of map/grep in a few cases more
Use block form of 'grep' i.e. 'grep {BLOCK} LIST' rather than
'grep(EXPR, LIST)' in filter_snapshot_fmts subroutine. This makes
code more readable, as expression is rather long, and statement above
there is 'map' with very similar expression also in the block form.
Remove unnecessary and misleading parentheses around block form 'map'
arguments in quote_command subroutine.
The inner "map" in format_snapshot_links was left alone, as it is not
clear whether adding parentheses or changing it into block form would
improve readibility and clarity of this code.
