It makes adding/deleting/modifying the entries easier, with one-line
editor operations. And if all data for one ID-to-quirk relationship is
on one line, with tabs to make for nice columns, I can more easily see
which device is linked to which quirk. That is why I usually prefer one
line per entry. And the entries in quirks.c are long, but not too long
for that IMHO.

I agree that the 80 columns restriction is a good thing in almost all
cases, as it limits the amount of information that is put on a single
line, and it limits the number of indentation levels within a function.

But in this case I think we are better off with one line per entry, even
if the line becomes longer than 80 characters. The information on one
line is not that much (one macro with 3 parameters), only the
identifiers try to be readable and discernible and therefore become

So this will only be a problem for terminals that are limited to 80
rows, and I do not think that anyone is that restricted nowadays.
