tests: make test-alias.t pass with re2...

tests: make test-alias.t pass with re2 Locally, these "non-ASCII character in alias" errors don't show up, though I get them when the alias is defined at the command line rather than in an hgrc. The brokenness comes from the fact that hgrcs are parsed with regexes, and re/re2 differ in this way: $ python -c 'import re; print(re.compile("(.*)").match("aaa\xc0bbbb").groups())' ('aaa\xc0bbbb',) $ python -c 'import re2; print(re2.compile("(.*)").match("aaa\xc0bbbb").groups())' ('aaa',) Apparently re2 stops when it encounters invalid utf8 (which I suppose makes sense given that '.' matches what appears to be a codepoint rather than a byte). This is presumably a bug in hg, but not very important, so just change the test to stick to valid utf8. Differential Revision: https://phab.mercurial-scm.org/D5288
