Re: Reading directory names with read-file-name

[Richard Stallman]

    However, one of the candidates for an improvement could be
    file-name-all-completions adding a third PREDICATE arg.
    However, I think that's still not feasible for the reasons
    I mentioned in my previous mail.

There is no need to get that discouraged!  You have pointed out a
complication, but a complication does not mean it is unfeasible.  It
just means a little more work is needed.

You can fix the file name handlers--in fact, they may not even need
any change.  Please take a look and see if they need any change.
