tools: escape dashes in the man pages

The portable way to have the dashes to be rendered as ASCII minuses is
to use the sequence backslash-dash, use this style at least for text
that can be copied and pasted (e.g. command names, file names, element
options).

Also use backslash-dash in the NAME section as suggested by lexgrog(1).
