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

Follow-up Comment #10, bug #61073 (project groff):

  The addition of:

 in '%1', path

caused the segmentation fault.

  The addition of " = NULL" for "path" fixed it.

  If I understand the code correctly, the searchpath::open_file(...)
tests the path for a NULL, so without it, there is an "endless" while
loop.
