[bug #61073] [groff]: SEGV with a single option as input

[Bjarni Ingi Gislason]

Follow-up Comment #11, bug #61073 (project groff):

  The "path" turned out to only contain something,
namely a single directory, when the DESC file was found.

  I wanted the whole search path to aid the user to find the problem.

  The patch in the attachment does that job and removes some trailing
space.
