Let roff_getname() end the roff identifier at a tab character
and audit all its callers whether termination is handled correctly. Resulting improvements: * An escape or tab ending the macro name in a macro invocation is discarded, and argument processing is started after it. * An escape or tab ending a name in ".if d" and ".if r" is preserved. * An escape ending a name in ".ds" causes the whole request to be ignored. * A tab ending a name in ".ds" becomes part of the string. * An escape or tab ending a name in ".rm" causes the rest of the line to be ignored. * An escape or tab ending the first name in ".als", ".rn", or ".nr" causes the whole request to be ignored. Kurt Jaeger <pi at FreeBSD> made me aware of https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=235456#c0 and in that bug report, comment 0 item (3) is a special case of this class of issues. Yes, the "mh" manual pages are no doubt among the worst on the planet.
