find: support all shell wildcards

[eavis]

GNU find version 4.1 says in its documentation:

>      -name pattern
>           Base of file name (the path with the leading directories 
removed)
>           matches shell pattern pattern.  The metacharacters (`*', `?', 
and
>           `[]') do not match a `.' at the start of the base name.
[...]

This is a bit ambiguous because it seems to say that shell patterns are 
supported but then says that only *, ? and [] are metacharacters - whereas 
the shell also has {}.  Anyway, find does not support {} shell wildcards:

% mkdir test
% cd test
% touch a b
% find . -name '{a,b}'
[no output]

For consistency I'd say it would be best for find's shell wildcards to be 
the same as those supported by bash (maybe a libwildcard is needed).  But 
anyway, if you do not intend to support {} wildcards, the manual page 
should make this explicit.
