For those that aren't, we use variable arguments because it shouldn't matter. Differential Revision: https://phab.mercurial-scm.org/D1372

bundle2: use os.SEEK_* constants Constants make code easier to read than magic numbers. I also threw in an explicit argument in a caller to further increase code comprehension. Differential Revision: https://phab.mercurial-scm.org/D1370

help: adding a topic on flags This is a short topic to explain how command-line flags can be specified. Some users have been confused by hg offerring different flag syntax than some other libraries, so it'd be nice to point them to this rather than explaining it every time.

py3: handle keyword arguments correctly in hgext/patchbomb.py The keys of keyword arguments must be str on Python 3 which is unicode. This patch make sure we pass keyword arguments with keys are str everywhere in this file and access the keys depending on whether they are bytes or str. This patch uses pycompat.{byteskwargs|strkwargs} and somewhere it also added r'' to prevent transformer from adding a b'' over there. Differential Revision: https://phab.mercurial-scm.org/D974
