For what it's worth, I'm also slightly in favor of 80.
Another possibility: no limit if it's unable to determine terminal
width, like in the pathologic case from Manfred Schwarb in the thread.
In general, output shouldn't be trimmed if it's redirected to a file.

- Macro-expansion-aware locations (not very useful for fortran, but
still very nice).
