Subject: Fix ambiguous regex in syntax highlighting.

This fix considerably speeds up syntax highlighting. It also avoids burning
100% CPU when typing long identifiers. Finally, identifiers longer than 20
characters are now properly highlighted, since the stack of the automaton
no longer overflows because of them.
