If values contain spaces, treat them as values

[mojodna]

Option names should never contain spaces; values might.

This (partially) works around #37, but still prevents individual negative values from being treated as values.

Thoughts?

You can use ' single quotes like --name 'foo bar'. I don't think I've seen behavior like what you're suggesting, but welcome to counterexamples. I want to stick to what would be familiar to people.

ogr2ogr is one the tools I was modeling behavior on (yes, it has weird options, but I wouldn't know how else to handle bounding box arguments).

E.g.

-spat xmin ymin xmax ymax

I've been using quotes in the meantime. Feel free to close this.
