Following options I want to be implemented, this to make it easier to do usual
things to commons things:

append=text:
Appends a string to the section/page

prepend=text:
Prepend a string to the section/page

Those sound doable, I'm on it.

sectionprepend=text:
Prepends a string to the section, but after the section header

That's probably not as easy, since it involves parsing the section text to some degree to find out what the section header is. I can't guarantee I'll implement this.

appendtext and prependtext parameters added in r36235. They work for sections too, although prependtext won't do what you expect (it'll prepend your stuff before the section header, appending your stuff to the previous section). Also, keep in mind that no newlines or spaces are added between prependtext, the old content and appendtext; if you want them, add spaces or newlines to the end of prependtext and/or the beginning of appendtext yourself.
