bracket-paste-magic adds backslashes inside a quoted string if URL is pasted ("regression" compared to pre-5.1 url-quote-magic)


I have the following snippet in my .zshrc:

  autoload -U url-quote-magic
  zle -N self-insert url-quote-magic
  autoload -Uz bracketed-paste-magic
  zle -N bracketed-paste bracketed-paste-magic

The latter two lines are only necessary for zsh ≥ 5.1, but don't seem
to do any harm for earlier versions.

Wth this configuration I noticed the following regression which has
probably been added with zsh 5.1: I can't reproduce it with 5.0.7 in
Debian Stable, but can reproduce it with 5.2 in Debian Unstable as
well as with the current git HEAD:

Pasting an URL, e.g.


into zsh with url-quote-magic activated resulted in the the following
commandlines with 5.0.7 (pasting starts with the URL, all other
characters were typed):

  % echo https://bugs.debian.org/cgi-bin/pkgreport.cgi\?src\=zsh

  % echo "https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=zsh

  % echo 'https://bugs.debian.org/cgi-bin/pkgreport.cgi?src=zsh

This is exactly what I expect: backslashes for quoting were only added
if no quoting using single or double quotes has been started already.

But with zsh 5.2 (and zsh git HEAD), it looks like this:

  % echo https://bugs.debian.org/cgi-bin/pkgreport.cgi\?src\=zsh

  % echo "https://bugs.debian.org/cgi-bin/pkgreport.cgi\?src\=zsh

  % echo 'https://bugs.debian.org/cgi-bin/pkgreport.cgi\?src\=zsh

While the first example still works as expected, I consider the latter
two examples to be some kind of regression. No backslashes should be
added in these cases.

But it only happens if I paste the full URL. It doesn't happen if I
just type the URL and it doesn't happen if just paste the "?src=zsh".
So I can imagine that this possibly is just a missing feature of
bracketed-paste-magic and not a real regression in url-quote-magic.
