sane-dll (5) man page missing

[jimav]

In Ubuntu 17.10, with packages "sane" and "libsane1" installed,

   man sane-dll
   man 5 sane-dll

say "No manual entry for sane-dll".

This man page is the SEE ALSO list in the sane(7) man page and mentioned
on the Internet.

Note: When trying to install libsane, apt-get substitutes "libsane1" for some reason:

# apt-get install libsane
Note, selecting 'libsane1' instead of 'libsane'
libsane1 is already the newest version (1.0.27-1~experimental2ubuntu2.1).

Thanks for taking your time to report this issue and help making Ubuntu better.

I found a corresponding bug report in Debian, so I have attached a bug watch. Looks like this might be fixed in the upcoming 18.04, but I haven't verified this yet.
