This is from the list of new features in bash-3.2:

f.  Quoting the string argument to the [[ command's  =~ operator now forces   
    string matching, as with the other pattern-matching operators.

The change was made for consistency -- without it, there is no way to have
the string matched without regard to characters significant to the matcher.
