The system's default browser for displaying HTML help pages is now used directly on Windows, instead of launching git-web--browser, which requires a Unix shell. Avoiding MSYS' bash when possible is good because it avoids potential path translation issues. In this case it is not too hard to avoid launching a shell, so let's avoid it. The Windows-specific code is implemented in compat/mingw.c to avoid platform-specific code in the main code base. On Windows, open_html is provided as a define. If open_html is not defined, git-web--browse is used. This approach avoids platform-specific ifdefs by using per-function ifdefs. The "ifndef open_html" together with the introductory comment should sufficiently warn developers, so that they hopefully will not break this mechanism.
