Instead of only snipping known "bad" directories to traverse (e.g., "3rd-party" and ".git"), also limit the search for text help files to just known "good" top-level directories: opal, ompi, oshmem.
This prevents accidentally traversing into VPATH build directories, for example, and finding PMIx and/or PRTE help files.
