That's all right.

For the above example yes, but not with more than one %():
“- %(capitalize "simple percent-escape")\n- %(capitalize "one more")”

Also non-greedy regexp is not enough here:
“%(capitalize "(some) text")”

When I wrote the patch my conclusion was that regexp alone is not
sufficient. For real feed templates used by me, not only for
artificial examples. I must admit that my solution with `forward-sexp'
is complicated but it makes available the power of the Emacs Lisp Mode
parser. Maybe there are still some simplifications?
