* wesnoth-mode.el (wesnoth-with-fake-insert): Removed. No longer necessary.
(wesnoth-preprocessor-closed-p): New function.
(wesnoth-complete-preprocessor): Use it. No longer requires temporary
preprocessor to be inserted.
(wesnoth-search-for-matching-tag): Added optional `skip' argument to skip
the first element.
(wesnoth-jump-to-matching): New optional argument `opening', to supply an
initial opening match instead of searching the buffer for it. Allows
`wesnoth-complete-preprocessor' to find matching, without a temporary string
being inserted.
