py3: mark all string literals in test-command-template.t as bytes # skip-blame because just b'' prefixes

py3: byte-stringify ValueError of unescapestr() to reraise as ParseError

py3: fix type of string literals in templater.tokenize() # skip-blame because just b'' prefixes

py3: drop b'' from error message generated by templater.runmember()

py3: fix join(), min(), and max() template functions over string It's silly to split a string into characters and concatenate them, but that should work and test-command-template.t has one. min() and max() had the same issue on Python 3, so fixed too.

py3: use startswith() to check existence of trailing '\n' in .hgtags file

py3: silence return value of file.write() in test-command-template.t

error: fix isinstnace check to use bytes instead of str Differential Revision: https://phab.mercurial-scm.org/D2528

py3: whitelist another nine passing tests I now see 347 tests passing[0] and 336 failing, so we're past halfway there. Hooray! 0: A few tests appear to regress in small ways (doctest output changes, for example) on Python 3.7.0a1, which is what I'm now using to test. That said, I'm pleased to report no major regressions. Differential Revision: https://phab.mercurial-scm.org/D2439
