[PATCH 1/3] msvcrt/tests: Don't pass path containing spaces to _spawnvp (try3)

[Piotr Caban]

Hi,
s
I've seen that this patch was marked as pending. I'm not sure what 
should I change in it. The argv[0] argument is not used in child process 
so maybe it will be clearer if I put some dummy value there. I can also 
change the tests to not use _spawnvp.

There's following comment near _spawnvp implementation:
Like on Windows, this function does not handle arguments with spaces or 
double-quotes.

Here are some results that shows what happens on windows when the tests 
are executed without this patch. The behavior on wine is similar.
E:\>msvcrt_crosstest.exe file

file.c:2027: Test failed: got '⌂' expected 'Hello worldHello worldHello 
world'
file: 791 tests executed (0 marked as todo, 10 failures), 0 skipped.

In the failing case
argv[0] = "a"
argv[1] = "a\msvcrt_crosstest.exe"
argv[2] = "file"

Thanks,
