py3: fix test-parse-date.t Differential Revision: https://phab.mercurial-scm.org/D5084

obsolete: don't translate internal error message AFAIK, it's caught only by "hg debugobsolete", so it's pretty much a programming error.

py3: get around unicode docstrings in test-encoding-textwrap.t and test-help.t On Python 3, docstrings are converted back to utf-8 bytes, which practically disables the "if type(message) is pycompat.unicode" hack in gettext(). Let's add one more workaround for the Py3 path.

crecord: make enter move cursor down to the next item of the same type Let's replace experimental.spacemovesdown with a separate key: Enter, since it wasn't used for anything in crecord. Not sure if '\n' works on Windows though. nextsametype() strictly only moves to items of the same type as the current item. This, for example, allows to go over individual lines in a diff and skip hunk and file headers (which would toggle multiple lines).

py3: build help of compression engines in bytes Removes "b''" from help.

py3: do I/O in bytes in test-help.t

tests: accept slightly different zip file in Python 3 I added some `unzip -t` here and I *think* the only change is from Python 3 having more data in the zip file headers or something. Sigh. Differential Revision: https://phab.mercurial-scm.org/D5075

webcommands: use stringutil.pprint() to repr invalid archive types Differential Revision: https://phab.mercurial-scm.org/D5074

archival: don't try and fsdecode non-{bytes,str} objects This function accepts both bytes and file-like objects. Differential Revision: https://phab.mercurial-scm.org/D5073
