Diff to previous 1.77 (unified)
Several improvements to escape sequence handling. * 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.
