Hallo!

I hacked a small patch (attached) implementing a comint-like interface
for history search in Eshell, and I would like to know what people think
about it. You may type 'M-r' in Eshell to try the interface.

I myself always miss the 'M-r' in 'M-x shell' whenever I use 'M-r' in
Eshell. I tried 'eshell-isearch-{forward,backward}', but IMO they are a
bit rough -- they are implemented by inserting the whole history file
into the buffer and overriding Isearch keys.

This patch is mostly copied from comint.el (or simple.el), and it is
basically a proof of concept. Before I submit it to the bug tracker, I
would like to gather some input regarding the change. Thanks in advance!
