doc: Document new behavior from 5a0307fb

[solj]

We no longer strip() the trailing whitespace from Probe output which can
result in different behavior than previous versions.

Is this really an intended change?

Btw: And I cannot find a strip() in the old code. Where was it removed? The only change I found in 5a0307f is in the group handling, that is now using a regexp to match the group names and strip trailing whitespaces in one step.

[AlexanderS]

Do we really want to document this as change? Or do we want to add a strip() so that the output is like before?

[solj]

@AlexanderS I believe it was an intended change so that the probes were technically accurate. In other words, I'm guessing someone had a Probe where they wanted the whitespace to stick around. I prefer the old way but I can see where one might run into problems if they care about the trailing whitespace.

[AlexanderS]

Maybe we want to strip the output by default, but add the possibility to flag the Probes that shouldn't be striped somehow?
