- \\ in high-level macro arguments

- .als only works for macros in mandoc, not for user-defined strings.

Currently, \\ is expanded in two situations:

Also, the "val" field in struct roffkv would have to be replaced

1) macro and string definition (roff.c setstrn())

with a pointer to a reference-counted wrapper, and an alias

2) macro argument parsing (mandoc.c mandoc_getarg())

would have to point to the same wrapper as the original.

For user defined macros, the second happens in time because of ROFF_REPARSE.

.als to undefined does nothing; the alias is not created.

But for standard high-level macros, it only happens after entering the

.rm'ing the original leaves the alias to point to the old value.

back to roff.c roff_res() from that point. Because this requires

Found in groffer(1) version 1.19

on the roff_res() level, it is hard to solve without the parser reorg.

These macros were used by the GNU grep(1) man page.

We should probably *not* add them to mandoc.

Just mentioning this here to keep track of the abuse.

This may not be the ideal solution after all: eqn(7) matrices

are lists of columns, so Avi's proposal would show each *column*

on its own *line*, which is likely to cause confusion.

A better solution, but much harder to implement, would be to

actually show the coordinates of column vectors on different

terminal output lines, using the clumnated output facilities

developed for .Bl -tag, .Bl -column, and also used for tbl(7).
