One of the changes between bash-3.1 and bash-3.2 was to unify the handling
of the pattern in the `==' and `=~' conditional command operators. Pattern
characters on the rhs are quoted to represent themselves (remove their
special pattern meaning). This is how == has always worked. If you remove
the double quotes and use backslashes to escape the spaces in the pattern,
you will get the match you want.
