The attached patch resolves the issue for me, but I'm not sure if it's
the best strategy. If possible, I think it would be better for
`eshell-parse-external-pipeline' to solely focus on finding the
external pipe operators ("*|", "*<", and "*>")[1] and then for
`eshell-rewrite-external-pipeline' to prepare the command string to
pass to sh. This would also have the advantage[2] of making it
possible to support a richer set of Eshell features with external
pipes, such as the following:

I think that sounds like a good idea (but I don't use eshell regularly,
so I don't really have much of an opinion here).  Perhaps John does;
added to the CCs.

CCing Sean as well, who implemented the extpipe module.

(I probably should have done that in the initial report, but I'm not sure the right way to CC people when I'm mailing bug-gnu-emacs@; if the CCed person replies normally, wouldn't it make a new bug number? I'm sure this is in the debbugs documentation though, so I should sit down and read it sometime.)
