PATCH: expansion
- X-seq: zsh-workers 11874

[ sunsite.auc.dk seems to be down, at least I don't get my mails
back... I'll just keep on sending patches ;-]
We were discussing these... This adds the style `suffix' and makes
`accept-exact' be used by _expand:
- With `suffix', expansion is not done if there is anything after a
`~foo' or `$foo'. I.e. it will not expand `~foo/<TAB>', but it will
expand `~foo'.
- With `accept-exact' set it will expand `$MAIL', with it unset, it
will not expand it (if there are other parameters starting with
`MAIL').
We were using rexexact in the old expansion code, so I thought we
should just use `accept-exact' which is the style equivalent of
recexact.
Note that I've used the same default value in _expand as it has
elsewhere (`false'), which means that without further configuring,
this now behaves differently. Should we make it default to `true' in
_expand?
Ok. Is this good enough? Oliver?
Bye
Sven
