Subject: [PATCH 12/92] fix "y" to work with NUL in the RHS
|
||
|
|
|
||
|
|
* sed/execute.c (do_list) [case 'y']: Handle NUL bytes
|
||
|
|
in the RHS of a y/LHS/RHS/ transliteration.
|
||
|
|
* testsuite/y-zero.good: New test-related files.
|
||
|
|
* testsuite/y-zero.inp:
|
||
|
|
* testsuite/y-zero.sed:
|
||
|
|
* testsuite/Makefile.am (SEDTESTS): Add y-zero here.
|
||
|
|
* testsuite/Makefile.tests: And here.
|
||
|
|
* NEWS (Bug fixes): Describe it.
|
||
|
|
The bug was reported by table@inventati.org,
|
||
|
|
with the execute.c change mostly by Paolo Bonzini.
