Bash Version: 3.2
Patch Level: 33
Release Status: release

Description:
        If a regular expression is quoted, it won't match the string. This is a 
change in behavior from 
        3.1.0 to 3.2.0. It is still present in 3.2.33.

Repeat-By:
        Execute:
        $ test="target/test"; [[ $test =~ "^target/" ]] && echo yes
        It returns 'yes' in bash 3.1.0 and nothing in 3.2.x

        Unquoted regexps do work in bash 3.1.0 and 3.2.x:
        $ test="target/test"; [[ $test =~ ^target/ ]] && echo yes
        It returns 'yes' in bash 3.1.0 and 3.2.x
