Okay, so subexpr is a string, not a regex.  That's what I 
was assuming.

Now you're contradicting yourself.  If subexpr is a string,
then replace_mid('aaa', 'a+', 'B') is 'aaa' (or maybe undef),
since 'a+' doesn't appear in 'aaa'.  But if you've changed
your mind since the previous paragraph and subexpr is a regex 
after all, then you're going to have to define what "nearest 
the middle" means a little better.
