cygwin: t3200-branch.sh fails with "List form of pipe open not implemented at -e line 22."

Now, how broken is that:

The message comes from one of the hooks, which are executed even
though they never meant to, because cygwin apparently uses file
content or name to detect executability (on FAT).

I just remove the hooks from repositories atm.

I think the bottom line is "don't use FAT".

I'm afraid I have to. NTFS isn't much better (newly created files
still have no correct attribute) and is slower (sometimes much
slower). Not that I have a choice, anyway: it's a typical corporate
workstation locked as down as possible.

Is this one of the hooks we ship as examples?  If so, that
means worse brokenness than just test failing.  It means that
the hook is not usable in your environment.

I presume it is this line in pre-commit sample hook:

    open $fh, "-|", qw(git-diff-index -p -M --cached HEAD);

Is Perl on Cygwin incapable of handle this in general, or is it
just what is on your machine being behind?

In the meantime, I've changed two things:

 - Earlier, tests run in a trash/ repository that was
   initialized with user's random templates.  This was *wrong*.
   It now uses freshly built templates that came from the
   source.

 - Further, hooks are disabled in the trash/ repository used for
   tests.  When we later add tests for hooks (HINTS, anybody
   ;-)), they can add their own anyway.

ActiveState's Windows port of Perl 5.8.6.

$ perl -e 'open $fh, "-|", qw(git-diff-index -p -M --cached HEAD)'
List form of pipe open not implemented at -e line 1.

I think it is not implemented because of Win32 lacking fork(2).
