If somebody needs to readd it he should make better code, specifically:
- Functions and variables necessary for supporting Control-P need to be defined
in a separate initialiazation function that is only called if Control-P was
found.
- Segments that show different information must be defined as separate segments
that may be put into configuration file.
- Segment functions must not know side they are on.
- Segment functions must not emit `priority`, it must go to configuration file.
- Segment functions must have proper documentation.
- Segment functions must not emit `width` and `align` keys.
- String `Loading...` or the equivalent must be overridable from configuration,
same for other interface strings (e.g. what is shown when `regex` is true).
- Segment functions must have names that make it clear what they emit.
