Re: PATCH: parse from even deeper in hell

> Oh I see, you renumbered a bunch of stuff in zsh.h, so text would be 
metafied differently now. But only metafy uses the table, unmetafy 
doesn't. That explains why the strings are different, but not why the 
old string causes an error. Unless we are parsing it before unmetafying 
it, which means any random bytes that weren't special before but are now 
would be interpreted specially. Can we unmetafy+metafy the string before 
lexing? I guess that might be slower though. (Sorry for the 500 mails).

Would some kind soul explain (if an explanation is possible) why the 
original string is not just saved verbatim? (Or maybe after history 
expansion is handled).  Why would a line in history not just be what it is?
