Subject: [PATCH] allopt() 

* FIX: some options are reset inside pipes and command substition         
       e.g. monitor and zle         
       those were displayed with wrong state 
* FIX: do not hardcode length for print out      
       thanks to pws: http://zsh.sourceforge.net/Guide/zshguide05.html  
* MOD: make it possible to throw s.th. like '_H-uP' at allopt
