Backtick cannot be escaped in double-quoted string

Backtick cannot be escaped in double-quoted string

When I write echo "\`abc'" instead of getting «`abc'» echoed I get prompt 
«dquote bquote>». Some time ago this construction worked normally. What may be 
the cause of such weird behavior? Zsh version 4.3.11-r1 («-r1» means that ebuild 
maintainers did huge enough changes to the ebuild to repost it), Gentoo amd64.

Hmmm... are you sure that's a real backslash and not just something that
looks like it?  Otherwise I can't see what the problem would be.

I'm not able to reproduce this with ZSH_VERSION = 4.3.11-dev-1 and
ZSH_PATCHLEVEL = 1.5241, so unless you have an alias for echo that
might be changing the parse, this looks like a Gentoo-induced bug.

necoro@Zakarumiy ~ % echo "\`abc'"
`abc'
necoro@Zakarumiy ~ % eix -e zsh
[I] app-shells/zsh
     Available versions:  4.3.10-r2 (~)4.3.11 4.3.11-r1
     Installed versions:  4.3.11-r1

Gentoo amd64 system here too.

So there is probably something wrong in one of your startup files :)

I found what is the cause: it is my experiments with histchars: I tried to use 
histchars[0]=$'`' because I really hate `!' expansion if it is mapped to `!'.
