Perl is really not native on Windows. Not only is there a performance penalty to be paid just for running Perl scripts, we also have to deal with the fact that users may have different Perl installations, with different options, and some other Perl installation may decide to set PERL5LIB globally, wreaking havoc with Git for Windows' Perl (which we have to use because almost all other Perl distributions lack the Subversion bindings we need for `git svn`). 2. As the Perl script uses Unix-y paths that are not native to Windows, the Perl interpreter has to go through a POSIX emulation layer (the MSYS2 runtime). This means that paths have to be converted from Unix-y paths to Windows-y paths (and vice versa) whenever crossing the POSIX emulation barrier, leading to quite possibly surprising path translation errors. 3. Perl makes for a rather large reason that Git for Windows' installer weighs in with >30MB. While one Perl script less does not relieve us of that burden, it is one step in the right direction. Changes since v4: - skipped the unrelated Coverity-appeasing patch. - replaced the cross-validation with the Perl script by a patch that retires the Perl script instead.
