[PATCH 3(a)/3] _man: Support _correct_word.



The 'compfiles' call in «man 8 foo<TAB>» resulted in glob patterns of the form
«.../foo*», so the would-be targets of spelling correction would not have been
provided to the completion code by the globbing code.

Fix this by mimicking the only other callsite of compfiles, _path_files, which
passes a flag (${_comp_correct:+"-"}) that is only set by _approximate and
causes cfp_opt_pats() to be skipped.  This enables spelling correction to work,
however, it is unknown what side effects it may have.
