Re: eshell/pcomplete suggestion: indicator for completion cycling

[Richard Stallman]

    Cycling completions means that the first TAB, instead of completing f
    to foo, inserts the first possible completion, foo1.  Hitting TAB
    again replaces foo1 with foo2, and again replaces that with foo3, and
    again goes back to foo1.

I am not sure that should be the default, since it might confuse
people who were not expecting it.  It certainly should not be the
default in eshell only, since that is inconsistent.  However, having
it as an option everywhere in Emacs would be good.  And maybe having
it as the default everywhere in Emacs would be good, I am just not sure.
