The patch structure has def_name component that is used to validate the
sanity of a "diff --git" patch by checking pathnames that appear on the
patch header lines for consistency. The git_header_name() function is
used to compute this out of "diff --git a/... b/..." line, but the code
always stripped one level of prefix (i.e. "a/" and "b/"), without paying
attention to -p<n> option. Code in find_name() function that parses other
lines in the patch header (e.g. "--- a/..." and "+++ b/..." lines) however
did strip the correct number of leading paths prefixes, and the sanity
check between these computed values failed.
Teach git_header_name() to honor -p<n> option like find_name() function
does.

Commit 969c8775 introduced a test which uses the non-portable construct:
command1 && ! command2 | command3
which must be
command1 && ! (command2 | command3)
to work on bsd shells (this is another example of bbf08124, which fixed
several similar cases).

We carefully verify that the input to git-apply is sane,
including cross-checking that the filenames we see in "+++"
headers match what was provided on the command line of "diff
--git". When --directory is used, however, we ended up
comparing the unadorned name to one with the prepended root,
causing us to complain about a mismatch.
We simply need to prepend the root directory, if any, when
pulling the name out of the git header.

Applying a patch in the directory that is different from what the patch
records is done with --directory option in GNU diff. The --root option we
introduced previously does the same, and we can call it the same way to
give users more familiar feel.

The end of a string is string[length-1], not string[length+1].
I pointed it out during the review, but I forgot about it when applying the
patch. This should fix it.

With "git apply --root=<root>", all file names in the patch are prepended
with <root>. If a "-p" value was given, the paths are stripped _before_
prepending <root>.
Wished for by HPA.
