windows: read all global config files, not just the first (issue4491) (BC) On windows, hgrc.d/*.rc would not be read if mercurial.ini was found. That was far from obvious from the documentation and different from the behavior on posix systems. As a consequence of this, TortoiseHg cacert configuration placed in hgrc.d would not be read if an old global mercurial.ini still existed. "hg config -g" could also crash when no global configuration files could be found. Instead, make windows behave like posix and read all global configuration files. The documentation was in a way right that individual config settings in the global Mercurial.ini would override settings from for example .hgrc.d\*.rc, but only because the .d files not would be read at all if a Mercurial.ini was found. The ordering in the documentation is thus changed to match the code.
