- The abort() in bufcat(), html.c, can be triggered via buffmt_includes()

by running -Thtml -Oincludes on a file containing a long .In argument.

Fixing this will probably require reworking the whole bufcat() concept.

- \\ 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.
