Bump to v0.8.3 from master - #1

…ename. Fixes jeremy-rifkin/libassert#123, related to davea42/libdwarf-code#279.

This could have been added directly in `print_frame_inner`, so we only
need to add it in one place. However, by adding it in `print_internal`,
prior to filtering, we allow transformation and filtering to cooperate.
This allows a transformer to modify a frame such that it can later be
marked for filtering, which would avoid duplicated code between those
functions.

I don't have this use case right now, but it made sense from an overall
product design perspective.

This closes #227. This closes #228.

Perf difference between this and #228 is nominal. Pick whichever you
like more.
