Mixed use of tabs and spaces

[cappe987]

Tabs and spaces are mixed throughout the code. Looks like you are using 4 spaces to correspond to a half tab (8 space tabs). For example this while-loop https://github.com/westermo/brist/blob/main/lib.sh#L127.
The loop is indented with 4 spaces. Next line is 1 tab (8 spaces). Next line is 1 tab + 4 spaces. And next line is 2 tabs.

This does not feel like a good way to handle indentation.

My approach to whitespace is pretty simple:

1. Press Tab key
2. Trust emacs(1) to do the Right Thing™

I'll admit that mixing spaces and hard tabs is a bit weird, then again it seems to be the default behavior in at least one editor. We could change it I suppose - but to be honest, it is very low on the priority list.
