Syntax Recognition

[Scott Turner <srt@UCLA-LOCUS>]

It would be nice if T would recognize the longest possible syntax when
scanning for syntax.  For instance, I currently have two macros:

	?X  -->  (*var* . x)

and 

        (?- head) -->  a prolog form

Unfortunately, the "?-" syntax doesn't work because the "?-" gets 
converted to "(*var* . x)" by the other syntax.  I think a better 
recognition algorithm would be to have the longest possible syntax 
recognized.
