* Bugfix:Ingo Schwarze2018-12-203-3/+8
| | | | | | | When after a \\, \t, or \a, another \t or \a had to be resolved in copy mode within the same argument, the argument got corrupted. Found while working on a loosely related bug report from Fabio Scotoni <fabio at esse dot ch>.
* Several improvements to escape sequence handling.Ingo Schwarze2018-12-157-8/+70
| | | | | | | | | | | | | | | | | | | | | | | * Add the missing special character \_ (underscore). * Partial implementations of \a (leader character) and \E (uninterpreted escape character). * Parse and ignore \r (reverse line feed). * Add a WARNING message about undefined escape sequences. * Add an UNSUPP message about unsupported escape sequences. * Mark \! and \? (transparent throughput) and \O (suppress output) as unsupported. * Treat the various variants of zero-width spaces as one-byte escape sequences rather than as special characters, to avoid defining bogus forms with square brackets. * For special characters with one-byte names, do not define bogus forms with square brackets, except for \[-], which is valid. * In the form with square brackets, undefined special characters do not fall back to printing the name verbatim, not even for one-byte names. * Starting a special character name with a blank is an error. * Undefined escape sequences never abort formatting of the input string, not even in HTML output mode. * Document the newly handled escapes, and a few that were missing. * Regression tests for most of the above.
* Now that we have the -Wstyle message level, downgrade six warningsIngo Schwarze2017-07-061-3/+3
| | | | | | that are not syntax mistakes and that do not cause wrong formatting or content to style suggestions. Also upgrade two warnings that may cause information loss to errors.
* Messages of the -Wbase level now print STYLE:. Since thisIngo Schwarze2017-07-0426-114/+116
| | | | | | | | causes horrible churn anyway, profit of the opportunity to stop excessive testing, such that this is hopefully the last instance of such churn. Consistently use OpenBSD RCS tags, blank .Os, blank fourth .TH argument, and Mdocdate like everywhere else. Use -Ios=OpenBSD for platform-independent predictable output.

* style message about missing RCS ids; inspired by mdoclintIngo Schwarze2017-06-175-0/+5

* Style message about legacy man(7) date format in mdoc(7) documentsIngo Schwarze2017-06-113-0/+3
| | | | | and operating system dependent messages about missing or unexpected Mdocdate; inspired by mdoclint(1).
* remove some instances of MdocdateIngo Schwarze2017-02-081-1/+1

* Finally port the OpenBSD regression suite.Ingo Schwarze2017-02-0834-0/+925
Both kristaps@ and wiz@ repeated asked for this, literally for years.
