[Patch] Clarify comment in diagnostic.c

[Wolfgang Bangerth]

I was tripped at least twice by a translated string that had invalid 
formats or had them in the wrong order. If that happens, we end up in a 
place with a comment that is really not very helpful, since it suggests a 
cause that has nothing to do with it. The following patch adds a sentence 
to that effect.

If someone approves it, I can commit this.

	* diagnostic.c (output_format) Mention another cause for an abort
	in the preceding comment.
