Greppable and short output

[AlexDaniel]

<AlexDaniel> grep: method get-message\(\$password\)\{
<greppable6> AlexDaniel, LLFourn/p6-AttrX-InitArg/README.md:13:    method get-message($password){␤LLFourn/p6-AttrX-InitArg/t/example0.t:11:    method get-message($password){

I think this could've been printed as two separated messages.

Right now it behaves a little bit differently:

<AlexDaniel> grep: method get-message\(\$password\)\{
<greppable6> AlexDaniel, https://gist.github.com/5dc24f4e3f934b8acde917e583c983a9

Should we actually attempt to print anything in the chat if there are ≤3 results?

The output is much better now:

<greppable6> AlexDaniel, 2 lines, 1 modules: https://gist.github.com/7020e771a297657ace4bf5e75b3b38d9

IMO that's good enough.

Looks correct, but it needs tests.
