Subject: 23.0.50; eshell/cd and multiple dots in directory name
--=-=-=
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
Your bug report will be posted to the address@hidden mailing list.
Please describe exactly what actions triggered the bug
and the precise symptoms of the bug:
Hello,
to reproduce:
$ emacs -Q
M-x eshell RET
$ cd /tmp
$ mkdir a...b
$ cd a...b
No such directory found via CDPATH environment variable
The error is caused by a call to `eshell-expand-multiple-dots' in
`eshell/cd'. I'm not quite sure what the use of
`eshell-expand-multiple-dots' is. A quick grep says it's only used in
`eshell/cd'. So I suggest the following short patch:

Diffs between working revision and workfile end here.

Actually I suggest to drop this confusing feature or at least implement
it everywhere in eshell (`eshell/ls', `eshell/cp', ...).
