For every example, sphinx-gallery outputs:

• One line stating it's going to run the example.
• One line stating it ran the example and how long it took.
• One blank line.
• The example and its runtime in a summary after all the examples are run.

That's at least 4 times as many lines as necessary. Plus there are 4 lines for every directory that's skipped.

This seems a bit too verbose. It would be much nicer if it followed sphinx's example and printed filenames on top of each other. When warnings come up, they get their own single line. The runtime summary is probably not really necessary by default, but once the above things are cut down, it wouldn't be as much of a problem.
