The branch main has been updated by kevans: URL: https://cgit.FreeBSD.org/src/commit/?id=75c3ca1ebf81224919f2b7a9edf2921ce76ea290 commit 75c3ca1ebf81224919f2b7a9edf2921ce76ea290 Author: Kyle Evans <kevans@FreeBSD.org> AuthorDate: 2022-08-23 02:08:03 +0000 Commit: Kyle Evans <kevans@FreeBSD.org> CommitDate: 2022-10-25 15:05:24 +0000 split: add some tests This should cover all of the basic functionality, as well as the recent enhancement to use a dynamic buffer size rather than limiting patterns and lines to MAXBSIZE.
