It turns out bkslash_in_varexp.tests was a bash bug :] ash and hush fail "corrected" bkslash_in_varexp.tests as well, just not as badly as I thought (hush gets half of the cases right). Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

# \] is not a valid escape for ] in set glob expression.
|
|
# Glob sets have no escaping at all:
|
|
# ] can be in a set if it is the first char: []abc],
|
|
# dash can be in a set if it is first or last: [abc-],
|
|
# [ and \ need no protections at all: [a[b\c] is a valid set of 5 chars.

|
|
# bash-4.3.43 misinterprets [a\]] as "set of 'a' or ']'".
|
|
# Correct interpretation is "set of 'a' or '\', followed by ']'".
