I do not think that you are being very fair with your criticism of my
handling of your patch.  In my patches list, I can see only one patch
from you, dated 29 Aug 2001.  The reason I put it on the back burner was
because of your description of it, which included:

and ends with the postscript:

From this description, I concluded that the patch was too premature,
and if I remember correctly, sometime about that time I was trying to
get the original author (who is also the author of "putty") of the DFA
syntax highlighting code to add support for multiline structures.

DFA syntax highlighting has been in jed for quite a number of years,
and may pre-date PCRE.  It works on all OSs supported by jed, including
VMS.
