two patches for 3 issues ;-)

[Patrick Winnertz]

Hello..

Since I'm the new mc maintainer in debian and I would like to get rid of 
many annoying bugs in mc I wrote two patches which will close several 
issues in the debian bugtracking system and/or several issues in the 
savannah bugtracking system. 

The first patch (fish_fix_whitespace.patch) will fix a issue that it was 
impossible to copy files via the fish vfs if the name of the file contains 
a space or starts with one. 
Furthermore it fixes a displaying issue, since such a file was displayed 
without the leading space.
This fix will close this Debian Bug: 461532

The second patch (escaping-issue.patch) will fix several 
escaping/unescaping issues in the internal cd and in the widgets. 
Furthermore is this patch needed by the first one, since the internal cp 
function via fish expects to get the string unescaped but get it in 
reallity escaped. So the unescape function is needed in order to fix this 
behaviour. 
Furthermore now it is possible to use tab completion for external commands 
on the subshell ( e.g. for a folder called "a /" the completion gave 
previously for example: "rm -rf a /" ... which is definitly not what was 
wanted *g*, now it escapes it correct and you'll get "rm -rf a\ /". 
This patch would close these Savannah Bugs: 16176, 18695, 14976
and these Debian Bugs: 326047, 458403


I'll hope that these patches will make it into the CVS. Thanks in advance.

Greetings
Winnie
