lexing

[Ray Andrews <rayandrews@xxxxxxxxxxx>]

Gentlemen:

The syntax highlighting in my editors makes the predictable mistake when 
it bumps into these:

(#b)
(#c1,2)
(#a3)

because the lexing mostly follows bash rules.  The people who write the 
highlighter are interested in fixing that for zsh, but they want a 
rigorous description of the rule.  As far as I know the only rule there 
is that if the hash is preceded by an open parenthesis then it is not a 
comment.  Is that sufficient or are there further subtleties?
