Omit spaces when using keyword arguments

[PatrickHaecker]

This shortens calls a bit more and lets keyword arguments win more often against positional arguments.

What do you think about always using keywords except for single argument case maybe? #12 (comment)

I think this is an interesting proposal for the 3-arg show. I kindly suggest to include this proposal into the general discussion to not split it between different issues/PRs.

For the 2-arg show it seems to be the right thing to remove the spaces around the = as this mostly only needs to be machine-readable.

I personally would strongly prefer Size(weight = 1, height = 2) than Size(1, 2) when both constructors exist, no matter 2/3-arg show. Maybe showrepr should be renamed to shortestrepr making the semantics more clear – ie that it's really about the shortest, not the most readable?
