* Fix three bugs regarding the interaction of \z and \h:Ingo Schwarze2022-04-271-1/+4
| | | | | | | | | | | | | | | | | | | | 1. The combination \z\h is a no-op whatever the argument may be. In the past, the \z only affected the first space character generated by the \h, which was wrong. 2. For the conbination \zX\h with a positive argument, the first space resulting from the \h is not printed but consumed by the \z. 3. For the combination \zX\h with a negative argument, application of the \z needs to be completed before the \h can be started. In the past, if this combination occurred at the beginning of an output line, the \h backed up to the beginning of the line and after that, the \z attempted to back up even further, triggering an assertion. Bugs found during an audit of assignments to termp->col that i started after the bugfix tbl_term.c rev. 1.65. The assertion triggered by bug 3 was *not* yet found by afl(1).

Consistently use OpenBSD RCS tags, blank .Os, blank fourth .TH argument, and Mdocdate like everywhere else. Use -Ios=OpenBSD for platform-independent predictable output.
* Finally port the OpenBSD regression suite.Ingo Schwarze2017-02-081-0/+16
Both kristaps@ and wiz@ repeated asked for this, literally for years.
