This reverts the parts of commit c8c9928eb1 that made translatability
worse rather than better. Changing "Error in column %2" to "%1 in column
%2" not only means that the translators have to check the i18n comments
to know what word hides behind %1, but there's also the problem that
the translator might need to translate "Error" in this context
differently from the standalone string "Error". Having to copy-paste
some HTML tags may be annoying for translators, but it's a far less
serious problem.
