It appears that `pwd` returns the POSIX-style or the DOS-style path
depending which style the previous `cd` used. To normalize, enforce `pwd
-W` in scripts.

Yes it probably does. Johannes said that he runs the tests outside of
the msysgit folder. That way there is only one path the submodule script
gets reported and not two like '/c/msysgit/git' and '/git'.
That would explain to me why it is passing.
I am afraid that the only solution is to patch msys itself to report the
long absolute path when passing window style paths to cd. Currently when
I do
cd c:/msysgit/git
I will end up in '/git' instead of the long path.
I found that there is a -W option to pwd in msys bash which makes it
always return the real windows path. A normalization in that direction
is unique and thus might be more robust. Have a look at the attached
patch. With this at least t5526 passes. I was not able to run the whole
testsuite properly at the moment. I can have a look at that tomorrow.
What do you think?
Cheers Heiko

Hello,
this is another patch that lives in msysGit for a long time.
Originally, it had two parts:
(Cf https://github.com/msysgit/git/commit/64a8a03 )
1) adding alias pwd='pwd -W' to git-sh-setup.sh
This one went upstream, though as a shell function.
2) revert of commit 4dce7d9b by Johannes Sixt <j...@kdbg.org>
This mingw-specific commit was created less than 3 weeks before
it was reverted. And it stayed reverted for two years.
Could you please either accept this patch, or revert 4dce7d9b ?
(Both alternatives are exactly the same.)
Have a nice day,
Stepan Kasal
