Fixes mis-applied patch in 5ecd6e4807d4b145a06e653dc1bb2f16678d0c14
The check was mistakenly changed to check file_name[0] when merging. The original intent was that since wcsrchr returns a pointer to the '\', if (file_name != NULL), we already know file_name[0] != '\0' because '\'!='\0'
The check was intentionally whether the *next* character, file_name[1], was '\0', i.e. whether szFullPath ended with '\' (was explicitly a directory).
Passing a directory is incorrect input (szFullPath should be a .tlb file), but for quality-of-implemnentation it still seems wrong to have this remove two path elements, e.g. currently "path\to\" truncates to "path\to" as if the last "\" delimited a resource id, then splits the filename yielding szHelpDir == "path" and file_name == "to", rather than szHelpDir=="path\to" and file_name == "" as seems intended (and as the originally-submitted patch would have).
