NAME:
     rdmatch
 PURPOSE: (one line)
     Read a standard name --- non-standard name correspondence file.
 DESCRIPTION:

     This program reads a file which contains a list of matches between
     informal and imprecise object names (typically from FITS headers)
     and formal, well-defined object names to be used by EPHEM.

     The file format has one pair of strings per line.
     The first string starts at the start of the line.  The second string
     starts at just after the ' character.  Each string is stripped of
     leading and trailing blanks (and tabs).

     These string pairs are collected into a pair of string arrays and
     then returned.
