Spurious warnings about MS-DOS paths

Spurious warnings about MS-DOS paths

[Ryan Johnson]

Hi all,

A recent cygwin update has started spewing warnings such as the 
following when I do tab completion on a path containing spaces:
> $ cd ~/Home/Documents/Pcygwin warning:
>   MS-DOS style path detected: ~/Home/Documents/PC\ reviews\ 2011
>   Preferred POSIX equivalent is: ~/Home/Documents/PC/ reviews/ 2011
>   CYGWIN environment variable option "nodosfilewarning" turns off this 
> warning.

Would it be possible to make the check exclude common character escapes?

Regards,
Ryan

No.  If a backslash has gotten to the filesystem layer which is
reporting this then something is going wrong.  Cygwin can't process a
file specification with a backslash as anything but a MS-DOS path.

No, but it probably is an upstream bug the bash-completion package worth
reporting and fixing.  Can you use 'set -vx' just before typing the
command that triggers the message, so I can see which command in the
completion function is insufficiently quoting the pathname such that a
glob completion is being inappropriately attempted on escape characters?

I don't have bash-completion(s) installed.

If set -vx would be useful with vanilla bash, I'm happy to try it, though.
