Emacs dired mode / dired-do-rename-regexp

Dear Mr. Kremer,

first of all I like to thank you for all your work you have done on dired-mode!

I have a problem when using %R (dired-do-rename-regexp). I like to use a kind of computed replacement string (with a Lisp expression), like it is possible with the normal replace-regexp command. This seems to be not possible, or do I make an error in masking the replacement string?

E.g.: when I specify the strings

Rename from (regexp): \([0-9][0-0]\) \(.+\)
Rename \([0-9][0-0]\) \(.+\) to: \,(+ \#1 3) \2

I get the message

"Invalid use of '\' in replacement text"

I'd appreciate your help. Is this my fault or are there plans to implement this into dired mode? I know that there is a workaround with wdired, but really would like to see it in dired itself.

Kind regards,

Ado Arnolds

dired-do-rename-regexp does not support \,, only \N and \&.  Try using
Wdired instead (C-x C-q).
