redrawhook issues

[danielshahaf]

The following issues should be fixed by the zsh redrawhook branch (#154 (comment)):
#90 #150 #154 #183 #203 #377

(confirmed for #90 and #150; the rest are known to be widget-wrapping-related issues, and the branch does away with widget wrapping)

The following issue probably won't be:
#40

edit: Upstream committed a patch that, in in conjunction with this issue, fixes #40, q.v.

The following issues might be fixed by using the zle -f yank / zle -f kill feature already in upstream zsh:
#150 #183

edit: #375 is also reported to be fixed by redrawhook branch, and #500 is suspected to be (not tested).

The zsh redrawhook branch was merged upstream in zsh-users/zsh@c3ea3ff, to appear in zsh-5.2.1 zsh-5.3.
