Probably this discussion won't solve anything, so let's leave it for
another time.

Here's the relevant code fragment:
(if (re-search-forward aname-re-str head-text-end-pt t)
(progn
(setq aname-str (match-string 2))
(setq head-text-nested (match-string 4))
(if (equal head-text-nested "")
(progn
(setq head-text-nested (create-heading-text))
(if (equal aname-str "")
(progn
(setq aname-str (create-aname head-text-nested))
(replace-match head-text-nested t nil nil 4)
(replace-match aname-str t nil nil 2))
(replace-match head-text-nested t t nil 4))) ;ERROR:
The top line above is the search. The last line is the replace-match
which fails. The couple replace-match lines above it might also fail...
haven't tested those yet.
create-aname is nothing but a set of setq's and a read-from-minibuffer.
create-heading-text is just a read-from-minibuffer.
So, yes, the search and replace-match are in the same function. Are
they "close together"? I'd say yes, but that's a judgment call really.
The string I want to replace in this particular instance is a null string.
