Review of said previous patch follows.  Sorry for the confusing diffs.

Trapping the "exit" in a subshell improves behavior.  I wonder why the
script does not use "false" or "(exit 1)"; the tests outside the
subshell have the same problem...

Unrelated: the --verify here does not have much effect on the upstream
of a pipeline.  Maybe "git log -1 --abbrev=7 --format=%h", or even
better, "git log -1 --format=%h" (for DEFAULT_ABBREV) would do the
trick.

An "exit" to avoid wasting time after a failing setup test might seem
appropriate, but I am happier to see it trapped by the subshell.

Likewise.

More missing SYMLINKS prerequisites.

To summarize, wherever you change behavior, it is improved.  Thanks.
