Fail early when writing to a fake file runs out of space. Makes debugging
tests easier.

Reads from files, on the other hand, are only buffering to a temporary
stream, so it makes sense to silently stop when they run out of space.

In the process I uncovered a testing bug in pack.subx: I was missing a
trailing space in the expected result, but the test still passed because
the space was getting truncated. Being principled about aborting on overflow
by default will help avoid such issues.
