The branch main has been updated by imp: URL: https://cgit.FreeBSD.org/src/commit/?id=4e52f5db352fe54d6ba342bcde01228096db8b19 commit 4e52f5db352fe54d6ba342bcde01228096db8b19 Author: Warner Losh <imp@FreeBSD.org> AuthorDate: 2021-07-31 05:19:58 +0000 Commit: Warner Losh <imp@FreeBSD.org> CommitDate: 2021-07-31 05:33:37 +0000 awk: Flag -Ft as deprecated behavior Upstream is poised to deprecate the -Ft wart in one true awk. None of the other awks do this, and the gawk maintainer says that he's had no requests for it in gawk in 30 years maintaining it. github can find a few instances of it in the wild. As such, warn that it's deprecated and will go away in the future.
