[formatter] Add support for spacing in a Map or List in the formatter

Reducing priority (this seems like a minor issue compared to more pressing problems with formatter).

Agreed, but keep in mind there are no minor issues for the formatter, because it's more a binary choice: either you can rely on it, or not So far I know I can't so I generally don't use it, but look forward to the day I'll be able to.

Hi Jean Noel, I understand your point of view.

In this case however, I guess the formatter presently just leaves the spacing around ":" alone, which means it doesn't at least mess up formatting that was manually made correct.

So I think the formatter could still be useful even without this issue fixed.

On the other hand were I to fix this issue without making it configurable, some people might well argue they want a space before the ":" as well and they might be more frustrated with the fixed version than with one that just leaves the spaces the way they put them manually.

So in that sense, I consider it almost better not to fix this right now, unless it can be configured.

But thanks for submitting, now it is on the record and... maybe someday there will be time to fix it.

Totally agree, there is no use in fixing this except in making it configurable. But IMHO a formatter is almost useless without dozen of configuration options That's why I suggested earlier to take these options from the Java preferences when they exist.

Will not get to for the 2.1.0 release.
