Re: [PATCH v2] t7400: add !CYGWIN prerequisite to 'add with \\ in path'

> Commit cf9e55f494 ("submodule: prevent backslash expantion in submodule
> names", 07-04-2017) added a test which creates a git repository with
> some backslash characters in the name. On windows, where the backslash
> character is a directory separator, it is not possible to create a
> repository with the name 'sub\with\backslash'. (The NTFS filesystem would
> probably allow it, but the win32 api does not). The MinGW and Git for
> Windows versions of git actually create a repository called 'backslash'
> in the sub-directory 'sub/with'.
>
> On cygwin, however, due to the slightly schizophrenic treatment of the
> backslash character by cygwin-git, this test fails at the 'git init'
> stage. The git-init command does not recognise the directory separators
> in the input path (eg. is_dir_sep('\\') is false), so it does not
> attempt to create the leading directories 'sub/with'. (The call to
> mkdir('sub\\with\\backslash') actually does recognise the directory
> separators, but fails because the 'sub/with' directory doesn't exist).

> In order to suppress the test failure (for now), add the !CYGWIN test
