This just came up yesterday, for pete's sake: http://lists.gnu.org/archive/html/bug-bash/2014-10/msg00197.html A longer explanation, with links to older bug reports: http://lists.gnu.org/archive/html/bug-bash/2014-03/msg00038.html The Posix interpretation that prompted the behavior change came in 2010: http://austingroupbugs.net/view.php?id=221 The current version of Posix says this about the substring removal word expansions, which use patterns in the same way as pattern substitution: "Enclosing the full parameter expansion string in double-quotes shall not cause the following four varieties of pattern characters to be quoted, whereas quoting characters within the braces shall have this effect."
