Package: emacs
Version: 24.3
I don't use eshell, so maybe this is how it is supposed to work, but
from the point of view of normal shells, this seems wrong:
foo=FOOBAR emacs -Q -f eshell
eshell> for foo in 5 { echo $foo }
-> FOOBAR
Cf:
bash> export foo=FOOBAR
bash> for foo in 5; do echo $foo; done
-> 5

Yes, indeed, this should be a bug. It's like that since at least 22.1; ie this is not related to your changes. ^ permalink raw reply [flat|nested] 8+ messages in thread

Actually I believe I fixed the issue. But that variable can be mentioned anyway, just not in this context. ^ permalink raw reply [flat|nested] 8+ messages in thread
