+- \\ in high-level macro arguments
+  Currently, \\ is expanded in two situations:
+  1) macro and string definition (roff.c setstrn())
+  2) macro argument parsing (mandoc.c mandoc_getarg())
+  For user defined macros, the second happens in time because of ROFF_REPARSE.
+  But for standard high-level macros, it only happens after entering the
+  high level parsers, which is too late because the code doesn't get
+  back to roff.c roff_res() from that point.  Because this requires
+  distinguishing requests, user-defined macros and standard macros
+  on the roff_res() level, it is hard to solve without the parser reorg.
