As pointed out by @niten94, empty lines in the man page are not just
unnecessary but also cause extra empty lines to be displayed with
alternative `man` implementations, e.g. `mandoc`. To test on Debian,
for example, mandoc's implementation is named `mman` and included in the
`mandoc` package.
Slight improvements to the man page, and the man page is now
provided in prebuilt binary tarballs. Also a .deb file is now
provided as an asset along with prebuilt binary tarballs.
