fix and improve debug for bin/md2html.sh and bin/gen-other-html.sh

Fix bogus USAGE debug messages in `bin/md2html.sh`.

Allow "about to run" debug messages for `-v 3` and higher
for `bin/gen-other-html.sh`.

In `bin/md2html.sh` changed VERSION from "1.1.2 2024-03-26"
to "1.1.3 2024-03-28".

In `bin/gen-other-html.sh` changed VERSION from "1.0.2 2024-03-26"
to "1.0.3 2024-03-28".

Tested the above using `make www` under Linux and macOS.
