for mentions, show full content text if it's small enough

[snarfed]

currently, mentions are rendered as:

X mentioned this post on [domain].

...which is fine, but if the mention post is a note and/or its content text is short enough - say, < 140 chars :P - it'd be nice to show the content text inline.

motivated by snarfed/bridgy#456, which now searches twitter and google+ for other people's posts that link to your site and sending them as mentions.

cc @aaronpk since we discussed this in irc just now.

when the mention content is too long, we should maybe also consider showing a snippet. options include p-summary if available, first N words or sentences, or the N words or sentences around the mention link. any actual context would be better than just "this was mentioned on X"!

(feel free to split this out into a separate issue if you want, of course.)

I was thinking about this. If an explicit p-summary is available, it should be used. I considered suggesting meta description as a fallback for p-summary, but that is hit or miss. I agree if the entry is less than 140 it could show the whole thing.

Isn't this addressed by @snarfed 's recent PR and therefore should be closed?

[snarfed]

sure! my PR doesn't do the snippet thing, only full content/summary, but still happy to close if we want.

[snarfed]

friendly ping on whether we should close this? up to you all.

[snarfed]

I'm thinking about this again. even for long mentions like articles, showing summaries or titles or snippets seems strictly better than just "X mentioned this on Y."

we don't recommend POSSEing articles with "I wrote a new article: [link]," we recommend including a summary or snippet or at least the title, right? i kinda feel like we should do the same with mentions.

(fwiw, this would also mean that they'd never be facepiled.)

thoughts? I'm happy to do this if you all agree.

reopening, this may have regressed...? i see the code still in master, but it's not happening for me with the latest release, 3.9.2.

example: https://snarfed.org/2019-01-17_snoopy#commentform . the one mention is way below 300 chars. its source URL https://brid-gy.appspot.com/post/twitter/schnarfed/1086002408428326922

[snarfed]

oh huh i can't actually reopen. @dshanske or @pfefferle mind reopening?
