[PATCH 00/10] Misc. cvsserver, dashless, and test suite patches

[Matthew Ogilvie <mmogilvi_git@miniinfo.net>]

This series of small patches fixes a few minor issues I noticed
while researching what it would take to for cvsserver to support
cvs's "-r" flags properly.  No real progress on the "-r" front,
but see comments in the "cvsserver: add comments about database ..."
email.

The "run test suite without dashed..." patch has wide scope,
even though is is fairly small.  It (along with fixing the things it
found in t2300 and t3409) was inspired by a desire to avoid future
regressions of the bug fixed in "cvsserver: run dashless 'git commands'"
patch, where git-cvsserver was trying to run dashed commands that
are not in the default PATH...

As this patch series was going to press, I noticed that
the "run test suite without dashed..." patch probably conflicts with
recently posted valgrind test suite patches.  See extra comments in
the email for possible resolutions.

The other patches in this series are mostly independent of each other.

When working on the "git-shell" patch, I noticed a couple of other
things related to "git-shell" that maybe ought to be changed (change
the argc==2 special case, and document the best way(s) to
configure an account to use git-shell).  See also extra information in
the email.
