Approved and applied.

Note - I made a few small changes.  I fixed the comments so that they
have two spaces after the full stop and before the closing */
I removed the calls to xexit (1) since the %F parameter to einfo()
already does this.  I also removed the word 'Aborting' from the error,
since this has a specific technical meaning,

Cheers
