In this format string, 15 is the 'width' (which controls padding), not
the 'precision' (which controls truncation).

To truncate beyond 15 without padding, specify a precision instead of a
width: "%>.15t".

So I'm not sure there's a bug here, or at least not the one you
describe.

What's not clear in the documentation is what happens when one specifies
< or > without an explicit precision, as in the example you give.  I'm
guessing this was the source of confusion here.  But I think this can be
addressed as a docfix.  Or am I missing something?
