mingw: do not crash on open(NULL, ...)
git-am: fix detection of absolute paths for windows
Side-step MSYS-specific path "corruption" leading to t5560 failure.
Side-step sed line-ending "corruption" leading to t6038 failure.
Skip 'git archive --remote' test on msysGit
Do not strip CR when grepping HTTP headers.
Skip t1300.70 and 71 on msysGit.
merge-octopus: Work around environment issue on Windows
