Squashable should point to some wiki (and maybe say what's the topic of the next squashathon too)

[AlexDaniel]

<AlexDaniel> squashable6: status <squashable6> AlexDaniel, Next SQUASHathon in 14 days and ≈10 hours (2017-10-07 UTC-12⌁UTC+14)

I think it would be better if it said:

Next SQUASHathon in 14 days and ≈10 hours (rakudo repo, 2017-10-07 UTC-12⌁UTC+14). More info: https://github.com/rakudo/rakudo/wiki/Monthly-Bug-Squash-Day

I think this is resolved in https://github.com/perl6/whateverable/commit/595e52e37bbefc2e2965d8c78be81cb080be7119.

<AlexDaniel> squashable6test: status <squashable6test> AlexDaniel, ⚠🍕 Next SQUASHathon in 5 days and ≈6 hours (2017-10-07 UTC-12⌁UTC+14). See https://github.com/rakudo/rakudo/wiki/Monthly-Bug-Squash-Day

It does not mention the repo but the message is already overloaded. Just having a link there is probably enough.

Maybe it's still needed, dunno.

It should print the current topic.

Relevant code: https://github.com/perl6/whateverable/blob/9c256087cde76967e5bb19710fde6c19c9e678d3/xbin/Squashable.p6#L63

We can easily parse the next cell too, but how do we get rid of markdown?
