Thanks.  I don't understand why we need to do this, but if we have technical 
limitations that force us to add those regular expressions then maybe it's not 
the end of the world (I understand that there is value in being able to 
selectively disable ligatures, using regexps or something else, but it seems 
surprising that we'll need extra Emacs-specific work for each and every font 
that includes ligatures).
