Subject: Re: are there any patches which add ~ expansion to rc
Reply-to: mkgardne@cs.uiuc.edu

Joe,

A while ago I hacked rc to add ~ expansion. (It was a real kludge.)
However, after thinking about it more I decided that expansion really
belongs in readline/editline. So I modified readline v2.1 to support
it. I then had to make a relatively minor change to rc to initialize
readline properly and to perform expansion.

[Caveat: I decided not to use ~ because of its obvious conflict with
pattern matching in rc. Instead I used % which seems to be free. It
would have been better if the final expansion was done in readline,
but it appeared that readline would be too easy to break.]

The modification works fine. I have to remember to use ~ instead of %
in emacs though! The patch is too long to post and is of (perhaps)
limited interest so I will email it to you directly.

Mark
