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. Signed-off-by: David Benjamin <davidben@mit.edu>
