No, it needs this squashed in (warning, whitespace damaged), except that 
the prerequisite EXPAND is nowhere defined - it is only a hint for you(?) 
that we need something else there because we don't have expand on Windows.

I don't know why the test with quotes fails. It must be a bug in MSYS 
bash, because the file system does not have any problems with quotes in 
file names.

Without the braces in this check the error message is still printed. I 
didn't test whether just writing 2>/dev/null first would suppress it as well.

BTW, I would prefer to keep the test in t3600 and t4135, that it doesn't 
happen for every other test script unnecessarily.
