[BUG][2.1.0b3] New command-line parser on Windows replace all \ with /

[Alexander Belchenko]

Hi John,

I found very bad problem in your new command-line parser/glob support 
for windows.

It's always replace back slashes with forward slashes even if this is 
not filename!!!

This is very serious regression for me, so please consider the bug 
report about this as highest possible importance.

Here is simple case:

C:\Temp>bzr init 5
Created a standalone tree (format: pack-0.92)

C:\Temp\5>bzr mkdir foo
added foo

C:\Temp\5>bzr st
added:
   foo/

C:\Temp\5>bzr mkdir foo\bar
added foo/bar

C:\Temp\5>bzr ci -m foo\bar
Committing to: C:/Temp/5/
added foo
added foo/bar
Committed revision 1.

C:\Temp\5>bzr log

There message should be "foo\bar" not foo/bar.
