I don't know about the isatty issue. I don't know much about the
underlying lower operating system level. But I'd like to note, that it
seems to work in *some* directories, but not in others:
[lisp] $ for f in ${ls} {echo $f}
2cyr.txt draw.el iso646-de.el single-frame.el
*much more output snipped*
[lisp] $ mkdir test
[lisp] $ cd test
[test] $ touch alpha beta gamma delta
[test] $ for f in ${ls} {echo $f}
Wrong type argument: listp, #("alpha beta delta gamma" 0 25 (escaped t))
[test] $ for f in ${ls -l} {echo $f}
total 0
usage: echo [-n] [object]
-n terminate with a newline
-h, --help output this help screen
Does anybody know offhand where in the eshell code `for' is implemented?
