bug#5516: 23.1.92; Bad alignment in dired

[Michael Albinus]

This bug report will be sent to the Free Software Foundation,
not to your local site managers!
Please write in English if possible, because the Emacs maintainers
usually do not have translators to read other languages for them.
The function `dired-align-file' works only, if the column position of a
file name is less than the column position of the file name in the
previous line. This assumption is not true, when the file list of
`dired' contains a mix of local and remote files. Example:

--8<---------------cut here---------------start------------->8---
(dired
 '("foo"
   "~/.emacs"
   "/ftp:anonymous@alpha.gnu.org:/gnu/emacs/pretest/windows/README"))
--8<---------------cut here---------------end--------------->8---

results in

--8<---------------cut here---------------start------------->8---

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'.
