I can't comment on your  elisp, as I am a lisp neophyte,  but it  
looks like ess-rep-regexp (found in ess-utils.el) is a wrapper around  
a normal regexp search and replace operation. It prevents the  
replacement from occurring within a string or single line comment,  
and provides some feed back when verbose is true.

Regarding the regex you are using, it won't catch the really  
malformed cases where the space only occurs on one side of the "=".   
Maybe you could use "[\t]?" instead of "[ \t]+".

Kind regards,
