aka
emacs -Q --eval '(setq eshell-cmpl-ignore-case t)' -f eshell

Thanks for the report, with similar symptoms to the closed
http://debbugs.gnu.org/5067.

This is a bug in pcomplete-insert-entry, which tries to delete
"/home/user/f" from a buffer that contains only "~/f", and so ends up
trying to delete the read-only prompt. There is a FIXME comment in the
source about this...

It works fine in 23.4, not in 24.1 and later.
