Compare proportional on Gitly to fixed on GitHub, same code.

However it's not what most people see in their editors. I wonder if anybody noticed or complained about it.
Two things that can go wrong with proportional code:
* Alignments like this
a = 1
long = 2
you can't do that unless your editor is very cooperative. That could make sharing code with coworkers difficult.* Sans serif fonts don't distinguish between I and l and I didn't find a proportional serif font that does look good enough for code.
