[rdiff-backup-users] a bug when using Cygwin

[Qiqi Yan]

Hi all,

I mentioned the problem in a previous post. But I think it might be better to 
start off a new topic for a little more attention, because it could cause files 
in the backup folder to go missing. It happens on rdiff-backup 1.1.7 with 
cygwin, and possibly other case insensitive platforms.

1. create file "a" in a folder.
2. run a backup with very default setting.
   now file "a" is created in the backup folder.
3. rename "a" to "A" in the source folder.
4. run a backup again.
   now you will find that neither file "a" or file "A" is in the backup folder!

strangely, if you start with an "A" file, and rename it to "a" in the second 
backup, the "a" file will still be in the backup folder.

I don't know if by using --override-chars-to-quote appropriately, this could be 
solved. Actually I never got --override-chars-to-quote to work on cygwin... 
anyone has any successful examples?

Best,
Qiqi
