[PATCH 0/4] Run test suite without dashed commands in PATH

This patch series runs the test suite without the dashed commands in the PATH. This improves the usefulness of the test suite as examples of how to do things, and more importantly, minimizes any possibility of regressions in bindir-installed scripts that might prevent them from working in a standard install where most dashed commands are not in the PATH (git-cvsserver was broken in this way until Sep 2009: d2feb01aa5).

The scripts in the "test-bin" directory that patch 3 creates can also be useful for manually testing a build of git without installing it; you typically don't need to set any environment variables (except maybe PATH) for the test-bin scripts to use the build properly.

Trivial note: This is a cleaned up resend of part of a hodgepodge cvsserver patch series that I sent last January.

---------

By the way, has anyone considered the possibility of splitting up the large directory at the top of the git source tree? I suspect that no one is interested, or it would have been done already, but I thought I would mention it anyway. Perhaps split off separate directories for libgit.a, builtins, other C-based excutables, test support executables, scripts, output execdir, and output intermediate (object) files for each of the other directories. Or some subset of these.
