Follow-up Comment #5:
Of course I transposed digits in the ticket number when writing the
uncorrectable commit message. Sigh.

[troff]: Warn on failure to adjust the output line.
* src/roff/troff/env.cpp (distribute_space): I planted an `assert()`
land mine for myself back in December and it finally went off. Remove
assertion that the amount of `desired_space` for adjustment must be
nonnegative. While rare, this can in fact happen with perverse inputs
such as long, unhyphenable character sequences or short output line
lengths. Throw new warnings in category "break" when adjustment is
desired but impossible: (1) the output line has no adjustable spaces
on it, or (2) any adjustable spaces would have to be squeezable/
shrinkable to achieve a fit, and that is not yet implemented in GNU
troff (see Savannah #44018). (Even if/when we do implement it, there
will be a [likely configurable] limit to how narrow an adjustable
space can become.)
* doc/groff.texi.in (Warnings):
* src/roff/troff/troff.1.man (Warnings): Document additional
circumstances under which warnings in "break" category are thrown.
Clarify existing circumstances.
Fixes <https://savannah.gnu.org/bugs/?66392>.
Also annotate places in code that I think will likely need to change
upon tackling Savannah #44018.
