I finally got around trying the regex suggestion (with the ?) and  
looking up TextWrangler's help. Neither worked. Both my fault:

(1)	That the regex didn't work is because I botched my "minimal  
example": instead of saying I wanted to replace f(x) by g(x)h(x) (for  
which of course the regex worked) I should have said I wanted to  
replace \f{x} with \g{x}\h{x}. In other words, I am trying to search  
for a command and replace it with two commands (*)

And none of the many variations I tried worked. My most surprising  
failure was (I was ready to insert the \ with a separate search.)

Given \f{x} in the text,
	Search for f{.*?} found it
	Replace with g{\1}h{\1} replaced with g{}h{} instead of with g{x}h{x}

(2)	That the reading suggestion didn't work should go without saying:  
as much as I loved TextWrangler for doing multiple file search and  
replace so transparently, I have a very hard time plunging into the  
middle of its help and make much sense of it.

Grateful---and hopeful---regards

  (*) I need to replace \NewTerm{blah} by \textbf{blah}\index{blah}  
(which is what \NewTerm does) because, occasionally, I need to edit  
to, say, \textbf{blahs}\index{blah} or  \textbf{blahs}\index{blah (to)}.
