Subject: [PATCH] Fix spurious diagnostic during extraction of . with
|
||||||
|
--keep-newer-files
|
||||||
|
|
||||||
|
Bug reported in https://savannah.gnu.org/bugs/?65838.
|
||||||
|
|
||||||
|
Bug introduced by 79d1ac38c1.
|
||||||
|
|
||||||
|
* src/extract.c (make_directories): Restore second argument. This
|
||||||
|
reverts the change made in 79d1ac38c1.
|
||||||
|
(maybe_recoverable, rename_directory): Update calls to make_directories.
|
||||||
|
* tests/extrac27.at: New file.
|
||||||
|
* tests/Makefile.am: Add new test.
|
||||||
|
* tests/testsuite.at: Likewise.
