doc: remove dashes

The use of dashes -- in general, but especially in our docs -- can be
problematic. It is used inconsistently and there is always another form
of punctuation that is as good or better for the situation. In an effort
to reduce the number of variations we use to display the same types of
information, remove the various uses of dashes from the documentation.
