[PATCH 1/4] t3509: use unconstrained initial test to setup repository.

[Pat Thoyts]

The first test did not run on msysGit due to the SYMLINKS constraint and
so subsequent tests failed because the test repository was not initialized.

[PATCH 2/4] t4120-apply-popt: help systems with core.filemode=false

[Pat Thoyts]

From: Johannes Sixt <j6t@kdbg.org>

A test case verifies that filemode-only patches work as expected. Help
systems where "test -x" does not work by applying the test patch also to
the index, where the effects can be verified even on such systems.

[PATCH 4/4] t5526: avoid dependency on submodule order

[Pat Thoyts]

When running tests on msysGit the actual results appear in the reverse
order. Added a test_cmp_unordered to test that each expected line is
present in the output without depending upon the order of lines.

I looked at the first three and think they are obviously fine.

As I mentioned, I would like to have a fix for the order in git-submodule. 
If you do not have the time, I will try to push aside some of the work I 
have to do here and investigate myself.

Ciao,
Dscho

I don't think that this is sufficiently portable.

Furthermore, just like Dscho, I'd rather prefer to know why the output is not 
ordered as expected.

I'm fine with the other patches as well.

A side note regarding SYMLINKS: It's actually possible to remove 70 of the 130 
SYMLINKS checks from the test suite:

Have you seen my response where I proved that it is a fflush() issue, most 
likely with mingw_spawn()?

Obviously, I haven't. Good catch!

[PATCH maint] start_command: flush buffers in the WIN32 code path as well

[Johannes Sixt]

From: Johannes Sixt <j6t@kdbg.org>

The POSIX code path did The Right Thing already, but we have to do the same
on Windows.

This bug caused failures in t5526-fetch-submodules, where the output of
'git fetch --recurse-submodules' was in the wrong order.

I think this is the correct fix.
