I tried to reproduce it on GNU Emacs (commit fafdfcb) and
failed.  However, I'm not sure whether I understood your report
correctly.  My Emacs doesn't seem to have
`lawlist-eshell-cmpl-compare-entry-function', only
`eshell-cmpl-compare-entry-function'.  Did you mean that variable?
I tried to set it to `'string-lessp', but nothing seemed to change after
"rm [space] [tab]" in Eshell.
