-- \\ 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.

+- .als only works for macros in mandoc, not for user-defined strings.
+ Also, the "val" field in struct roffkv would have to be replaced
+ with a pointer to a reference-counted wrapper, and an alias
+ would have to point to the same wrapper as the original.
+ .als to undefined does nothing; the alias is not created.
+ .rm'ing the original leaves the alias to point to the old value.
+ .de .als .de changes both, but
+ .de .als .rm .de only changes the new value, not the alias.

+- roff string condition comparisons fail when vars contain quotes:
+ .ds s '
+ .if '\*s'' \&...
+ hard to fix because of the basic architecture (string replacement
+ happens before roff(7) syntax parsing)
