sed: treat '\x5c' as literal backslash
Sed incorrectly treated '\x5c' (ASCII 92, backslash) as an escape character.
Old behavior:
$ echo z | sed -E 's/(z)/\x5c1/' # identical to 's/(z)/\1/'
z
New behavior:
$ echo z | sed -E 's/(z)/\x5c1/'
\1
Reported in https://bugs.gnu.org/30794.
* NEWS: Mention bug fix.
* sed/compile.c (normalize_text): Pass backslash as literal character.
* testsuite/misc.pl: Add tests.
