in repository groff.

commit c41b8ce7fc8ba507ded9f0c606b0346ee769091b
Author: G. Branden Robinson <g.branden.robinson@gmail.com>

    [m4]: Fix Savannah #62775.
    
    * m4/groff.m4 (GROFF_URW_FONTS_CHECK): If Ghostscript or awk are
      unavailable, skip only the prepopulation of the URW font search path
      instead of the entire check.  This way we still locate the URW fonts
      if they are in one of several standard locations.
    
    Fixes <https://savannah.gnu.org/bugs/?62775>.
    
    This commit does _not_ update indentation, for clarity.
