Bash Version: 3.2
Patch Level: 48
Release Status: release

Description:
        Bash allows escape characters to be embedded by using the $'\n'  
syntax. However, unlike all other $variables,
        this doesn't work with embedded newlines. I think it should.

Repeat-By:
        X="a$'\n'b c"
        echo "$X"

        expect to see:
                a
                b c

        actually see:
                a$'\n'b c


Fix:
        $'\n'  should be expanded within double-quotes, like other variables 
are. 
        Otherwise, please correct the man-page to make it clearer.

        If this is a feature, not a bug, then is there a better way to include 
newlines in a variable-assignment?
        The syntax    X="a"$'\n'"b c"    will do it, but that is really really 
ugly.


Thanks,

Richard
