Development notes

My brain is too small. I'm putting stuff here to remember it later.

Remove useless spaces before and after parentheses:

 :%s/(  */(/g
 :%s/  *)/)/g

Add spaces where I want to see them:

 # After commas
 :%s/,\([^ ]\)/, \1/g
 # Inside = + += > etc.
 :%s/\([a-zA-Z0-9]\)\([-+*/><=]\|[-+*/><=!]=\)\([a-zA-Z0-9]\)/\1 \2 \3/g
