Convert manpage to mandoc and fix usage

In all honor, the previous usage was formally more correct, but for the
sake of consistency across all the tools having the v-flag, I separated
it from the command-string.

Also, make use of the mandoc macros for the manpage. This makes it
easier to maintain, extend and change in the future.
