Replace more [BR] with rst bullet lists

Replace more [BR] with rst bullet lists

Make the console output format rst-style bullet lists nicely, and use
these instead of [BR] tags to create proper bullet lists in program help
texts.  The produced output looks much nicer in all the output formats
(including the console) compared to what it was before any rst changes.

Now the number of [BR] tags remaining is relatively low, and can fixed
at some later time.
