End-of-sentence spacing

[Dorai Sitaram]

groff pretty much forces one to use two spaces after sentence-ending 
punctuation, unless it's at the end of a source line. Is there a way to avoid 
this, so that the space is uniform regardless of whether the ending punctuation 
occurs mid- or end-line?  (I could resign myself to always type 2 spaces after 
every sentence, but convention has moved away from this type of unergonomic 
typing, and it's difficult to do it just for groff.)


Apologies if there is a known solution for this in the archives. Very difficult 
to search for the keywords to this problem.


Thanks,
