$ /bin/sh
$ foo=abcdef; echo "${foo#'ab'}"
abcdef
which is incorrect. One should get:
$ foo=abcdef; echo "${foo#'ab'}"
cdef
(like with ksh93, mksh, bash, posh, zsh and yash).
POSIX says:
The following four varieties of parameter expansion provide for
substring processing. [...] 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.
