Similar message templates have been consolidated so that translators need to work on fewer number of messages. * ja/i18n-similar-messages: i18n: turn even more messages into "cannot be used together" ones i18n: ref-filter: factorize "%(foo) atom used without %(bar) atom" i18n: factorize "--foo outside a repository" i18n: refactor "unrecognized %(foo) argument" strings i18n: factorize "no directory given for --foo" i18n: factorize "--foo requires --bar" and the like i18n: tag.c factorize i18n strings i18n: standardize "cannot open" and "cannot read" i18n: turn "options are incompatible" into "cannot be used together" i18n: refactor "%s, %s and %s are mutually exclusive" i18n: refactor "foo and bar are mutually exclusive"
