Just did some tests and noted that the shell and git does not support 
them. I guess I thought that they work because [:alpha:] matched "a".

Hi Robin

The bash shell doesn't support [:alpha:] too:
$ mkdir test
$ cd test
$ touch a
$ touch b
$ touch :
$ ls [:alpha:]
:  a

The fnmatch function of the python module fnmatch 
(http://docs.python.org/lib/module-fnmatch.html) does not support 
:alpha: too.

example:
$python
 >>> from fnmatch import fnmatch
 >>> fnmatch("a","[:alpha:]")
False

So I see no reason for displaying a warning.

Best regards,
Florian
