Here is how I would write it, I think. It seems
to work at least when inserting or removing the
tag is concerned.
If it gets more complicated, you might want to
factor out the searches (the
`re-search-forward's) and put them into
a `let', then check the associated values if
they are nil or not (see the help for
re-search-forward how to make it not report an
error on no hit), and then move point to
(match-beginning 0) - but only if you feel the
need to, using re-search-forward "inline" if
you will is a fine way to do it as well.
See answer one for comments what I did.
Except for [[:alpha:]] which I didn't mention.
In answer two there are some other comments.
This is answer three :)
(defun emacs-wiki-unlink-toggle ()
(interactive)
(save-excursion
(if (looking-at "[[:space:]]")
(goto-char (1- (re-search-forward "[[:alpha:]<]")))
(goto-char (1+ (re-search-backward "[[:space:]]"))))
(let*((nop "<nop>")
(nop-len (length nop)))
(if (looking-at nop)
(delete-char nop-len)
(insert nop)))))
