We just need to skip the (...) and perform autocompletion as before.
Shift pos by 1 in the whole function so we don't have to look 2 characters
back (makes the function easier to read).
Functions contain pointers in their return values - remove them before
searching for the type.
Also restrict the searched variable/function/type tags a bit only to
types which make sense for the search.
