core/load-fragment: be more precise in error messages
Whenever a message fails, mention the offending word, instead of just giving the whole line. If one bad word causes just this word to be rejected, print only the word. If one bad word causes the whole line to be rejected, print the whole line too. https://bugs.freedesktop.org/show_bug.cgi?id=56874
