[SOLVED] How to prevent `fmt` shell script from adding double space after end of sentences?

Issue

I use the fmt shell script for line wrapping in several editors of Mac OS X. I'm generally satisfied with it, except one thing—double space after end of sentence. (These days few people do that, right? That seems really old schooled, at least to me, and wastes the precious space of eighty columns.)

I know there's a -d chars option for fmt (documentation) which specifies the sentence-ending sentinels, so currently I trick the script by -d @, noting that @ seldom enters the scope. It works, but I guess there are some better solutions rather than this tricky one? Is it possible to set chars following the -d to a real empty list?

Solution

-d '' works for me:

fmt -d '' <<< $'Do not.\nDouble-space.'
