This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

==============================

Starting from `emacs -Q', Eshell cannot complete a directory if the
completion target is on the same line before it:

    $ ls ~/Dropbox/ ~/Dro

does not complete, even though there is a completion target. The
following *does* produce the correct completion:

    $ ls ~/Dropbox/Work/ ~/Dro

The following, however, does not:

    $ ls ~/Dropbox/ ~/Dropbox/Work/ ~/Dro


Thanks,

Joost Kremers



==============================


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
For information about debugging Emacs, please read the file
/usr/share/emacs/24.3/etc/DEBUG.

(This was reported 7 years ago but unfortunately never got a reply at
the time.)

I can reproduce this on current master, using emacs -Q.

I don't believe this is a bug, but a feature as they say.

This behavior is controlled by `eshell-cmpl-use-paring'

After setting the custom to a non-nil.

(setq eshell-cmpl-use-pairing nil)

Will turn on the desired behavior:
    $ ls ~/Dropbox/ ~/Dropb<Tab>
    $ ls ~/Dropbox/ ~/Dropbox/

Makes sense.  So since this is working as designed, I'm therefore
closing this bug report.
