util: reference __main__ in sys.modules as a sysstr

ui: convert to/from Unicode on Python 3 in ui.editor() I considered making this I/O be done in terms of bytes, but that would cause an observable regression for Windows users, as non-binary-mode open does EOL conversion there. There are probably new encoding dragons lurking here, so we may want to switch to using binary mode and doing EOL conversion ourselves.

manifest: refer to bytestrings as bytes, not str Required on Python 3.

manifest: use node.hex instead of .encode('hex') The latter doesn't work on Python 3.

pure: use int instead of long Similar to the recent 73aa13bc8dac (revlog: use int instead of long, 2017-03-19).

histedit: inline cleanupnode Move "cleanupnode" (unsafe strip) into "safecleanupnode" so it's impossible to call the unsafe function directly. This helps reduce future programming errors.

histedit: use safecleanupnode in _aborthistedit (issue5500) Now nobody in histedit calls the unsafe cleanupnode directly.

histedit: use safecleanupnode in _finishhistedit This simplifies code a lot.

histedit: add a method to cleanup nodes safely The new method will decide between: - cleanupnode, which calls the unsafe repair.strip - create obsmarkers Ideally, nobody calls "cleanupnode" directly except for "safecleanupnode".

py3: prove hg status works

localrepo: use node.hex instead of awkward .encode('latin1') Spotted as an option by Yuya. Thanks!

py3: prove hg config works

templater: make pad() strip color codes before computing width (issue5416) Tested in ANSI mode. We might have to extend _ansieffectre to support terminfo mode.

templater: make pad() compute actual width str.ljust() and .rjust() are based on byte length, which are valid only for ASCII characters.

templater: reject bad fillchar argument passed to pad() Otherwise TypeError would be raised.
