Subject: Start of View Post Info.
X-Git-Url: https://www.chiark.greenend.org.uk/ucgi/~ian/git?a=commitdiff_plain;h=2357a937893efdfe30b9f6e8a2908196653c624b;p=mastodonochrome.git

Start of View Post Info.

Currently it just shows the post in the ordinary way, without all the
extra detail. But it's plumbed through the menus, which is a start.
