[PATCH 11/11] shell32: _SHAppendToUnixPath() refactor and remove Resource ID string matching code

[Rob Walker]

The only call(s) to this function, with a Resource ID string, have been removed from
_SHCreateSymbolicLinks(). So we can remove support for this.
Correctly handle a zero length base path string (which would segfault the pre-existing
implementation).
