Re: bracketed paste - chopping trailing newlines
% fgrep 5.0.9 *
bracketed-paste-magic:# Starting with zsh-5.0.9, ZLE began to recognize the "bracketed paste"
url-quote-magic:# As of zsh-5.0.9, the following may also be necessary in order to apply
to get the most intuitive behaviour possible the bracketed paste code
would need to consider what the parser thinks about the current line.
If we assume, that this information is not available, then, stripping
a newline if the previous character is not a newline (even though
I mentioned that I would prefer not stripping them) in combination with
the described possible behaviour if a paste immediately follows an other
one, might lead to the most intuitive behaviour that can be archived

I noticed that GNU screen does not support bracketed paste. Expecting
average zsh users to know which zsh version they run and if they
disabled bracketed paste might be reasonable, but also expecting them to
know which of their terminals support bracketed paste seems to be a bit
too much, given that many people only paste seldom. If it is thus not
that unusual that users might not know if bracketed paste is currently
enabled, then being able to distinguish between pastes and running
commands in an obvious way by enabling highlighting by default seems to
be more important to me.

This is a very interesting idea and I might use a variant of it in my
~/.zshrc. I don't think that this would be adequate as default
behaviour, though, since it breaks the assumption users could have that
a pasted command never runs without being acknowledged first, but YMMV.

I assume your prototype was not meant to handle all corner cases in
a perfect way, but other than that, it's a good fit for my personal
needs, thanks :)
