Man pages not installed

[tartley]

The docs at http://docs.ctags.io/en/latest/index.html describe themselves as "developer oriented docs", and point users to ctags.1 man page. But the snap does not appear to install any man pages. (whereas the .deb does)

Man pages aren't generally instalable by snaps. We could perhaps install some inside the /snap directory and document a custom man -l /snap/... command to view them. But that's fugly and hard to discover.

Alternatively, wherever the place is that we would document that custom man command (either 'snap info' or the snap's store page), then instead, simply include the end-user documentation there, or a link to it.

Add this omission of installed man pages to the "snap limitations" section
