3Remove extra whitespace from a text file.
4
5When I copy/paste text from the web into Obsidian, it's often inserted
6with a lot of additional whitespace, e.g. text like
7
8    hello\n\nworld
9
10becomes
11
12    hello\n\n  \n\nworld
13
14This script cleans up some of this extraneous whitespace for me.
