} Why don't you use C-y? This works for me:
} fly% ls foo bar[Esc-Backspace][C-y]
} erases and returns bar on the line.

Yes, but:

% ls foo bar[esc-backspace][esc-backspace][c-y]

erases and then returns "foo bar".  What I want to do is erase "foo bar"
and then return only "foo".  "Undo" is the closest approximation.

} Furthermore, all the kills enter the
} kill-ring and are reaccessible.

Doesn't help, because "foo" isn't in the kill ring all by itself, it's
in the same kill-ring entry with "bar".

} Do you have any hints?

WORDCHARS has always bugged me because it does NOT specify characters that
are word *breaks*, it specifies characters *in addition to alphabetics and
numerals* that are *included* in words.

So you need to *remove* characters from WORDCHARS to get them to be taken
as word breaks.  That's why this thread started with a patch to default
WORDCHARS to nothing at all.
