annotate common/portpath.h @ 633:6c090638b2b4

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Use static buffer for module file name. According to the msdn examle the return value of getmodulefilename should be used to indicate success and not the size. And according to comments on that function on Windows 8.1 it does not return the needed size. So better be more robust and just use max_path as a limit.
