Since nearly its birth, git's tags have included a "tagger" field which
describes the name of tagger, email of tagger, and date and time of tagging.
But, this field was only loosely tested by git-mktag. Provide some thorough
testing for this field and also ensure that the tag header is separated
from the tag body by an empty line to reduce the convenience of creating
a flawed tag.

This fixes the same breakage in diff-files.
Signed-off-by: NJunio C Hamano <gitster@pobox.com>

Earlier, if you changed a staged path into a directory in the work tree,
we happily ran lstat(2) on it and found that it exists, and declared that
the user changed it to a gitlink.

This is wrong for two reasons:

 (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
     exist anymore, as far as the index is concerned.

This fixes these breakages in diff-index that the previous patch has
exposed.

diff-index and diff-files can get confused in corner cases when an indexed
blob turns into something else in the work tree.  This patch adds tests to
expose such breakages.

The test is classified under t2XXX series instead of t4XXX series, because
the ultimate objective is to fix "add -u" (and "commit -a" that shares the
same issue).

It seems that git prune changed behaviour with respect to revisions added
from command line, probably when it became a builtin. Currently, it prints
a short usage and exits: instead, it should take those revisions into
account and not prune them. So add a couple of test to point this out.

We'll be fixing this by switching to parse_options(), so add tests to
detect bogus command line parameters as well, to keep ourselves from
introducing regressions.

This actually sounds like a bug in cvsps, which requires an existing
home directory when asked for the usage through -h

 $ HOME=/nonexistent cvsps -h
 Cannot create the cvsps directory '.cvsps': No such file or directory

This made t9600 think that cvsps is not available if HOME did not exist,
causing the tests to be skipped

 $ HOME=/nonexistent sh t9600-cvsimport.sh
 * skipping cvsimport tests, cvsps not found
 * passed all 0 test(s)

Now t9600 sets HOME to the current working directory before checking for
the availability of the cvsps program.

This changes the pattern matching code to not store the required final
/ before the *, and then to require each side to be a valid ref (or
empty). In particular, any refspec that looks like it should be a
pattern but doesn't quite meet the requirements will be found to be
invalid as a fallback non-pattern.

This was cherry picked from commit ef00d150 (Tighten refspec processing,
2008-03-17), and two fix-up commits 46220ca1 (remote.c: Fix overtight
refspec validation, 2008-03-20) and 7d19da46 (refspec: allow colon-less

  git-p4: Use P4EDITOR environment variable when set
  git-p4: Unset P4DIFF environment variable when using 'p4 -du diff'
  git-p4: Optimize the fetching of data from perforce.

We tightened the refspec validation code in an earlier commit ef00d150
(Tighten refspec processing, 2008-03-17) per my suggestion, but the
suggestion was misguided to begin with and it broke this usage:

    $ git push origin HEAD~12:master

The syntax of push refspecs and fetch refspecs are similar in that they
are both colon separated LHS and RHS (possibly prefixed with a + to
force), but the similarity ends there.  For example, LHS in a push refspec
can be anything that evaluates to a valid object name at runtime (except
when colon and RHS is missing, or it is a glob), while it must be a
valid-looking refname in a fetch refspec.  To validate them correctly, the
caller needs to be able to say which kind of refspecs they are.  It is
unreasonable to keep a single interface that cannot tell which kind it is
dealing with, and ask it to behave sensibly.

This commit separates the parsing of the two into different functions, and
clarifies the code to implement the parsing proper (i.e. splitting into
two parts, making sure both sides are wildcard or neither side is).

This happens to also allow pushing a commit named with the esoteric "look
for that string" syntax:
