I was about to resend with s/\$/*/g and ignored this issue (with a
note) then it occurred to me we can simply ignore these long lines
from column width calculation. Yeah such a line may still be wrapped
around, but it will not push every other line to the far right. We
already have code for that in adjust_refcol_width()
max = term_columns();
...
/*
* rough estimation to see if the output line is too long and
* should not be counted (we can't do precise calculation
* anyway because we don't know if the error explanation part
* will be printed in update_local_ref)
*/
if (21 /* flag and summary */ + rlen + 4 /* -> */ + llen >= max)
return;
...
we can limit max to, like, term_columns() / 2 (or 2/3 of
term_columns). There's no perfect number, some people will still find
the output ugly _often_. But hopefully the majority won't. What do you
think?
