Note about Zwei

In Zwei/Zmacs, a certain simple heuristic is used to speed up parsing
buffers full of Lisp code: any line that begins with an open parenthesis is
taken to be the beginning of a top-level Lisp expression.  If you have an
open parenthesis at the beginning of a line and it is NOT the beginning of
a top-level expression, you will confuse the editor's parsing very badly.
Many people seem to have been confused by this behavior.  This heuristic
may be stupid, but without it parsing of the buffer would be unacceptably
slow; we all have to put up with it.
