Problem with question mark in the filename

[Hartmut Figge]

Greetings,

i know that this is not the right place to open a bug, but i do miss a
guide 'how to submit bugs for mc' on
http://www.midnight-commander.org/wiki. ;)

Often i download patches for SeaMonkey and get files with a question
mark. One example is
https://bug579736.bugzilla.mozilla.org/attachment.cgi?id=458928. Using
wget to fetch this patch gives a file with the name
attachment.cgi?id=458928.

My build script for SM will automatically apply this patch. If i wish to
disable a patch for the next build a convenient way is to rename the
file by prefixing the filename with an x.

mc should be able to do this. But. *g*

Here is a testcase.

Create a new temp dir and change to it. Then issue
touch a1?b2
mc
Navigate to a1?b2 and press F6
a ESC TAB Home x gives xa1?b2 as intended
The filename changes to xa1a1?b2b2 after confirmation.

This result isn't really that one which was wanted. I am using

hafi at e675 ~ $ mc --version
GNU Midnight Commander 4.7.3
