Message:

Add edit:help command for zsh-style in-edit help

zsh has this convenient feature where pressing M-h while typing a
command will look up the man page for the current command and fully
restore your editting session afterwards.

This command brings a similar feature to BarnOwl. Instead of launching
man, we open the usual popwin, which is much easier to restore from.
