tests: quote environment variable to extract wildcard on MinGW environment On MinGW environment, the command line below in test script can't extract wildcard "*" and remove target files correctly. $ rm $ENVVAR/foo/bar.* To extract wildcard, environment variable should be quoted by double quotation like below: $ rm "$ENVVAR"/foo/bar.* This patch also omits "-f" of "rm" to know whether files are removed or not by exit code of it.

tests: choose the path separator in PYTHONPATH suitable for platform Before this patch, test code introduced by e3a5922e18c3 into test-extension.t always uses ":" as the path separator in PYTHONPATH. But ";" should be used on Windows. This patch chooses the path separator in PYTHONPATH suitable for platform.

util: warn when adding paths ending with \ Paths ending with \ will fail the verification introduced in 684a977c2ae0 when checking out on Windows ... and if it didn't fail it would probably not do what the user expected.
