Allow Maintenance::error() and Maintenance::fatalError() to take
StatusValue objects. They now print each error message from the
status on a separate line, in English, ignoring on-wiki message
overrides, as wikitext but after parser function expansion.
Thoughts on the previously commonly used methods:
- $status->getMessage( false, false, 'en' )->text()
Almost the same as the new output, but it allows on-wiki message
overrides, and if there is more than one error, it prefixes each
line with a '*' (like a wikitext list).
- $status->getMessage( false, false, 'en' )->plain()
- $status->getWikiText( false, false, 'en' )
As above, but these forms do not expand parser functions
such as {{GENDER:}}.
- print_r( $status->getErrorsArray(), true )
- print_r( $status->getErrors(), true )
These forms output the message keys instead of the message text,
which is not very human-readable.
The error messages are now always printed using error() rather
than output(), which means they go to STDERR rather than STDOUT
and they're printed even with the --quiet flag.
