Details:

Lines like the following are improperly parsed by enscript 1.6.4:

sed 's/^\s*#*\s*PORT=[1-9][0-9]*/PORT=1691/' $SYSEDGE_INIT~ | uniq >
$SYSEDGE_INIT

Everything after the hash/pound in the regex gets pretty-printed as though it
were a comment.  On my system, I copied c_string.st to a new state, which I
called sh_string.st:


/*
 * Read one sh-string.  sh-styled strings are needed in many languages.
 * Therefore it is implemented in a separate file to ease its reusing.
 */

state sh_string extends Highlight
{
  /\\\\./ {
    language_print ($0);
  }
  /\"|'/ {
    language_print ($0);
    return;
  }
}


/*
Local variables:
mode: sh
End:
*/


Then I changed sh.st to call sh_string instead of c_string:


  /* String constants. */
  /\"|'/ {
    string_face (true);
    language_print ($0);
    call (sh_string);
    string_face (false);
  }


This seems to be an imperfect solution, but it works for the time being.
