qdoc: erratic behavior on link text formatting

QDoc attempts to style both generated autolinks and explicit \l links to functions in a specific way; "\l foo()" is rendered in html as

<a href="page.html#foo">foo</a>()

I.e. '()' are moved outside the link. But this breaks in some other cases, e.g.

\l

Results in

<a href="page.html#foo">The foo</a>() function

The link text is cut at '()' which was not intended.
