PSA: Please wrap "```" around logs in Github issues

[Jens Alfke]

Hey folks,

When you paste a log or backtrace into a Github issue, please put a line of three back-quotes before and after it. That tells Github's Markdown parser to treat it as pre-formatted text and ignore any special characters like "_" or "*" in it. It also stops it from misinterpreting a Cocoa stack frame index (a "#" followed by a number) as a reference to another issue — this is particularly awful because it spams links to it all over the low-numbered bugs in the project and there's no way to remove them. :(

[Or, if the dump is really long, consider pasting it into a Gist or Pastie or whatever and just linking to it.]

Example of doing it right (from this issue):

```

19:35:15.805410 HTTP:  #249: POST /db/_bulk_docs

2014/01/16 19:35:15 http: panic serving 127.0.0.1:36089: interface conversion: interface is nil, not float64

goroutine 333 [running]:

github.com/couchbaselabs/sync_gateway/rest.(*handler).handleBulkDocs(0xc2013f6de0, 0xc200b24ce0, 0x0)

```

Without the back-quotes, this text gets messed up — note that some of the "_"s were hidden but caused the text after them to go italic:

19:35:15.805410 HTTP: #249: POST /db/bulkdocs
2014/01/16 19:35:15 http: panic serving 127.0.0.1:36089: interface conversion: interface is nil, not float64

With them, the text is correct and everything's nicely formatted in monospace:
