To include angle brackets in paren syntax class. Basically, we only need 
to consider these and the straight parens when converting a method 
definition into a method call with placeholders, so using an 
otherwise-empty syntax table seemed appropriate when I wrote the above code.

It seems that I should only change the current syntax table only around 
the `backward-sexp' and `parse-partial-sexp' calls there, but not when 
doing any text modification.
