Subject: 24.5; Cannot rename files in directory with escaped spaces

[Message part 1 (text/plain, inline)]

most of this happens outside of emacs:
mkdir 'escape\ me'
cd 'escape\ me'
touch a
emacs -Q .
C-x C-q
rename the file from a to b
C-c C-c

when I inspect the error, it looks like it is attempting to rename
/home/mjrosenb/tmp/escapeme/a to /home/mjrosenb/tmp/escapeme/b
which fails, because the name of the directory is 'escape\ me', not
'escapeme'

Hi,

and thanks for the report.

However, it seems to work just fine on GNU Emacs 25.1.50.6 (commit
ac9a931).  It might have been fixed in the meantime.

Best,

Strange, I just checked out git master, and reproduced it (I
used e0400b72a24). Did you both quote and escape the space? (alternately,
you can run mkdir escape\\\ me)  I've reproduced this on both an ubuntu
system, an arch-linux system, and a gentoo system.  I haven't tried on a
redhat based system, nor on OSX.

Addendum: I have discovered that there are multiple ways to rename a file
in dired.  I simply deleted the a, and replaced it with a b, while dired
was in Editable mode.

You are right, I see it too.

AFAICS, the problem is in wdired-normalize-filename: it removes the
backslash and the following blank from the name, thus creating a name
of a file that doesn't exist.

Should be fixed in commit 02bf7cc.
