I find gmane.emacs.bug incredible "hard" to read.  Threads seem to
randomly stop and start again (w/o gnus finding the parents) and purely
administrative messages pop up every now and then.

Back to the topic:  not giving the pipelined processes a TTY will
prevent similar problems w/ non eshell builtins.  And in most cases it
should be faster as well, e.g. GNU libc uses line buffering on a TTY.

But probably we should first find a way to disable this for the last
command in the pipeline.  This is already done in
`eshell-do-pipelines-synchronously' (do we really need compat code for
Emacsen w/o `start-process'?).  I'll try to figure out how to do it
right.
