I am using refer (grefer) with numbering format. So if a reference 
is at the end of the sentence, I need to put a period (.)right after
the citation. I cannot put it right after ".]" since it will make
the number not to be superscipt. I need to putt he period at the 
beginning of next line.

But troff treats every line starts with "." as a command line and this
line will be ignored. I tried several possible ways and the only 
woprk around I have now is to put "\ " in front of the period. But 
that introduices an extra space between the citation of the period.

Does anyone know how to do it?

Thanks.
