" This is a bit more complicated, because function arguments can be passed in a
" very similar form on how attribute sets are defined and two regions with the
" same start patterns will shadow each other. Instead of a region we could use a
" match on {\_.\{-\}}, which unfortunately doesn't take nesting into account.
"
" So what we do instead is that we look forward until we are sure that it's a
" function argument. Unfortunately, we need to catch comments and both vertical
" and horizontal white space, which the following regex should hopefully do:
"
" "\%(\s\|#.\{-\}\n\|\n\|/\*\_.\{-\}\*/\)*"
"
" It is also used throught the whole file and is marked with 'v's as well.
"
" Fortunately the matching rules for function arguments are much simpler than
" for real attribute sets, because we can stop when we hit the first ellipsis or
" default value operator, but we also need to paste the "whitespace & comments
" eating" regex all over the place (marked with 'v's):
"
" Region match 1: { foo ? ... } or { foo, ... } or { ... } (ellipsis)
