 anylink.py: Looks for designated prefixes like DW_ADDR etc.
   Used by other code, this was never that useful alone.

+  As of February 2014 it disallows a backslash inside an identifier,
+  forcing a token break.  This is closer to Latex
+  hence useful where we have  \DWTAGfoo\DWTAGbar

 formlink.py: Using anylink.py, this transforms DW_FORM_ into
