Just to clarify, I thought that the error being raised should have been
subclassed, because it was a different type of error, which always has 2
filenames. I wasn't advocating for if/else adding a plural. So my
feeling was that a too-generic exception was being raised. However, I'm
fine with "File(s)" for generic exceptions that don't know how many will
be there.

(Especially if you try to i18n to something like Polish that has
different rules for *1, *2-3, *4-6, ... I don't remember the specifics,
but IIRC you have groups like (1, 11, 21, 31) and (2,3, 12,13, 22,23,
...) I think gettext() has support for some of that stuff.
