i18n: look translation of both "DEPRECATED" and "(DEPRECATED)" up
Since 44cc9f63a2f1, deprecated commands, options and so on are
detected by "(DEPRECATED)" instead of "DEPRECATED".
"hg.pot" generated from recent source files doesn't contain msgid
"DEPRECATED", and looking the translation of "DEPRECATED" up in
up-to-date *.po files works incorrectly.
But on the other hand, there are still old *.po files, which contain
msgid "DEPRECATED" but not "(DEPRECATED)". Looking the translation of
"(DEPRECATED)" up in such old *.po files also works incorrectly.
This patch resolves this problem by looking translation of both
"DEPRECATED" and "(DEPRECATED)" up.
This should work correctly, because previous patch makes "deprecated"
checker be applied only on translations, of which msgid contains exact
"(DEPRECATED)" string.
'p.msgstr' examination in 'deprecatedsetup()' is needed to ignore
untranslated entries. This also makes 'deprecatedpe.msgstr'
examination in 'deprecated()' meaningless.
# This is a randomized test that generates different pathnames every
# time it is invoked, and tests the encoding of those pathnames.
#
# It uses a simple probabilistic model to generate valid pathnames
# that have proven likely to expose bugs and divergent behavior in
# different encoding implementations.
