Commit dbd0f5c7 (Files given on the command line are relative to $cwd,
2008-08-06) only fixed git-commit and git-tag. But, git-apply and
git-fmt-merge-msg didn't get the update and exhibit the same behavior.

Fix them and add tests for "apply --build-fake-ancestor" and
"fmt-merge-msg -F".

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().

Add a comment showing how to include a web link (i.e. gitweb/cgit)
and a patch in the email that is sent for each pushed commit.

The quoting was tricky enough that it's worth documenting.  To add
two blank lines (i.e. put \n\n in the printf), you would need to
say \\\\n\\\\n, and in the end, the pair of "echo" statements seemed
better.  This is used in glibc.git repository:

GCC 4.4.0 on Windows does not like the format %zu.  It is quite unlikely,

We need getpass() to activate curl on MinGW.  Although the default

provide curl support, so getpass() is used.

no space.

Usually, the argh element in struct option points at a placeholder value
(e.g. "val"), and is shown in the usage message as

    --option=<val>

by enclosing the string inside of angle brackets.

When the option is more complex (e.g. optional arguments separated by a
comma), you would want to produce a usage message that looks like

    --option=<val1>[,<val2>]

In such a case, the caller can pass a string to argh with placeholders
already enclosed in necessary angle brackets (e.g.  "<val1>[,<val2>]")
and set this flag.

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
(&quot;, &amp;, &lt; and &gt; 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.

It is convention that argv should be terminated with NULL, even if
argc is used to specify the size of argv. setup_revisions() requires
this and may segfault otherwise.

This patch makes sure that all argv (that I can find) is NULL terminated.
