Hmm.  Indeed, something is treating "!" as additionally special.  The
interesting part is that it does not always treat the first character of
the $HISTCHARS variable as special, nor does it treat ! as special when
it is not the first character of $HISTCHARS.

Or (more likely) internally somewhere is explicitly un-quoting file
expansion characters but is not doing so for history characters.  This
could probably be fixed but might take a while to trace down.

} I'm on Zsh 5.02, Ubuntu 14.04 x64 and Fedora Rawhide x64. One possible
} solution on my end is to define the aliases like this:
} 
} Heptagon% alias 'gc!'="git commit --amend"
} Heptagon% alias 'gc\!'="git commit --amend"

Sure, that's fine as long as you never want to be able to type gc\! to
prevent the first alias from expanding.  Or the patch I sent should
apply to _expand_alias in 5.0.2.
