Keybase.pub improperly handles files with %20 in the name

Currently have an example available at keybase.pub/flaeme
You can see I have a file called The%20Lift.mp3 in it. The link however doesn't escape the %20 though and when you try to follow it it looks for a file called "The Lift.mp3" which doesn't exist. You need to URL escape the file names, essentially.

Start by reproducing the example at keybase.pub/flaeme and follow the link for The%20Lift.mp3. Trace how keybase.pub builds links for filenames containing %20; done means the link resolves to the existing file named The%20Lift.mp3 rather than looking for The Lift.mp3.
