* Support two-character font names (BI, CW, CR, CB, CI)Ingo Schwarze2021-08-108-19/+50
| | | | | | | | | | | | | | | | | | | | | | | | in the tbl(7) layout font modifier. Get rid of the TBL_CELL_BOLD and TBL_CELL_ITALIC flags and use the usual ESCAPE_FONT* enum mandoc_esc members from mandoc.h instead, which simplifies and unifies some code. While here, also support CB and CI in roff(7) \f escape sequences and in roff(7) .ft requests for all output modes. Using those is certainly not recommended because portability is limited even with groff, but supporting them makes some existing third-party manual pages look better, in particular in HTML output mode. Bug-compatible with groff as far as i'm aware, except that i consider font names starting with the '\n' (ASCII 0x0a line feed) character so insane that i decided to not support them. Missing feature reported by nabijaczleweli dot xyz in https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=992002. I used none of the code from the initial patch submitted by nabijaczleweli, but some of their ideas. Final patch tested by them, too.

* The GNU tbl(1) program contained in the groff package internallyIngo Schwarze2020-10-252-2/+2
| | | | | | | | | | | | | | | | | | uses roff(7) tabulator settings to implement tables, and it used to leak the changed tabulator settings from tables to the subsequent roff(7) code. In mandoc/tbl_term.c rev. 1.54 (June 17, 2017), code was added to be bug-compatible with groff. In commit d0e03cf6 (Oct 20, 2020), GNU tbl(1) changed behaviour to save the tabulator settings before starting a table and restore them afterwards. Adjust mandoc for compatibility. Since mandoc implements tables without using roff(7) tabulator settings, saving and restoring tabulator settings is not needed in mandoc. Simply deleting the code that changed tabulator settings by reverting tbl_term.c rev. 1.54 is sufficient in mandoc. Also adjust the desired output of the regression tests to match the new behaviour of both groff and mandoc.

Consistently use OpenBSD RCS tags, blank .Os, blank fourth .TH argument, and Mdocdate like everywhere else. Use -Ios=OpenBSD for platform-independent predictable output.
