test-hgweb-diffs: partially adapt for Windows Since chmod isn't supported on Windows (or vfat), I'm importing a here-doc instead (<<EOF ..). Option --bypass on import of the here-doc is required on Windows (or vfat) to bypass the working directory (see hg help import). Not using --bypass would lose the mode changing bits. I've had to insert a --bypass on the preexisting import call futher down in the test, because importing a patch with --exact and mode changes will fail on Windows (and vfat). As the point of this test is not to test commit, I'm using the import procedure for all platforms unconditionally, that is, I'm intentionally not keeping the original sequence of hg and chmod calls for platforms that support exec either, which saves us having to insert an #if exec ... #else ... #endif.
