Hi Stefan:

Actually I opened the initial issue because there is a rust-ts-mode now
in vanilla and in my opinion it is a bit incoherent to have a native
mode to support rust, but don't support compiling rust.

Specially considering that adding such support seems extremely simple,
it only requires to improve the regex to be a bit more strict. And the
one I provided is buggy mainly due to the "too free" wildcard I used to
match anything including the new line...

Just improving the [^\0]+?--> in the regex; I thing everything will work
properly.
