Shell substitution with quotes in bash-4.1

[Corentin Peuvrel]

Hello,

I found a bug in bash-4.1 (CentOS 6) that was fixed (at least) in 
bash-4.3 (Fedora 21).

$ foo=aXb ; echo "$BASH_VERSION : ${foo/X/\'}"
4.3.33(1)-release : a'b

$ foo=aXb ; echo "$BASH_VERSION : ${foo/X/\'}"
4.1.2(1)-release : a\'b

The shell substitution add the backslash before the quote, but it 
shouldn't (and ${foo/X/'} fail because it wait for an ending quote).

I was wondering if it was possible to backport a fix in 4.1 ?


Thank you,
