diff3 under windows does not work for files which contain brackets

[Alexander Sokolov]

Hello,

diff3.exe utility fails comparing files which names contain bracket,
like "1(test).txt"

Example:

files to be compared directory
=========================================================

Directory of C:\usr\1

07.12.2009 21:42 <DIR> .
07.12.2009 21:42 <DIR> ..
07.12.2009 21:06 26 1(s).txt
07.12.2009 21:05 19 2.txt
07.12.2009 21:05 27 3.txt
3 File(s) 72 bytes

diff utils bin directory
=========================================================

Directory of c:\usr\2\bin

07.12.2009 21:23 <DIR> .
07.12.2009 21:23 <DIR> ..

C:\usr\1>c:\usr\2\bin\diff3.exe 2.txt 3.txt "1(s).txt"
c:\usr\2/bin/diff.exe: '1(s).txt': No such file or directory
c:\usr\2\bin\diff3.exe: subsidiary program `c:\usr\2/bin/diff.exe'
failed (exit
status 2)

=========================================================

Notes:
diff.exe works with such files.
Linux version works with such files.
Old 2.7 (from unxutils) diff3.exe works with such files.

Thanks,
Alexander
