[erlang-questions] printed maps look confusing

Removing the spaces doesn't work at all. Example:

#{<<"hello">>=><<"bye">>}

Adding a space after the comma is OK but when pretty printing over lines 
of 80 characters it's going to make things a lot worse.

The current solution sounds best to me. Just gotta get used to it.
