-#### Behaviors of the minify option
-
-- removes any unnecessary separator character between arguments/commands
-- removes `;;` from the last value in a case
-- removes unnecessary quotes on arguments
-- transforms unnecessary manipulations (e.g. `${VAR}`) into simple variable call
-- brace blocks or subshells with a single command will be replaced by said command
-- reduces level 1 `$()` subshells to use backticks
-- escaped dollarsigns are un-escaped
