Huh?

$ echo {"x,x"} # expected result: '{x,x}'
x,x
$ echo $BASH_VERSION
3.1.17(3)-release

That doesn't look like '{x,x}' to me... it looks like 'x,x', which by my 
reading is wrong.

If I had to guess, I'd say bash sees the {}'s, and incorrectly decides 
to do brace expansion based on the *quoted* comma... but when it 
actually does expansion, it gets the (correct) result 'x,x', except that 
now the {}'s have been incorrectly removed.
