This is a simpler workaround alternative to D958, "i18n: clean msgcache when
encoding changes." The cache won't be bloated unless you run tons of commands
with different --encoding options on command server, or serve many repositories
of different web.encoding options on hgweb.
The test was originally written by Jun Wu.
Differential Revision: https://phab.mercurial-scm.org/D1053
I mainly did the simple cases, like removing ".. note::", changing single
quotes to double quotes and adapting underlining.
Unhelpful msgstr in fuzzy entries are removed. (They were suggestions by the
program msgmerge.)
Existing tool like "msgfmt --check" can check typical translation
problems (missing "%s" in msgstr, for example), but can't check
Mercurial specific ones.
For example, "msgfmt --check" can't check whether the translated
string given to "ui.promptchoice()" is correct or not, even though
problems like below cause run-time error or unexpected behavior:
- less or more choices than msgid,
- choices without '&', or
- choices with '&' followed by none
This patch adds the tool to check Mercurial specific translation
problems in *.po files.
