Hi,

I discovered this strange behavior of eshell in emacs 23.1.1 (on MacOSX and
Debian Lenny, both built from source, launched with '-q').

It seems that the presence of two slashes ("//") in a path breaks the
search:

Example:

~ $ export PATH=/usr//bin
~ $ which m4
which: no m4 in (/usr//bin)
~ $ export PATH=/usr/bin
~ $ which m4
/usr/bin/m4
~ $


I mailed this to johnw@gnu.org (maintainer of eshell) who told me that it
seems to be an Emacs issue.

Cheers,
