Instead of completely disabling them, we now use their internal toggle.
Also moved `drawwhitespace` commands inside the plugin.
---
* Fixed bug where commands would show even when plugin was disbled. Also removed antiquated way of disabling.
* Fixed typos.
* Also moved trimwhitespace out of config, if it already has a default enabled value of false.
* Changed documentation.
* Clarified comments.
When multiple substitution kinds are present in the same line, they're
placed in the cache in an order that's spatially consistent only between
items of the same kind.
Because we stopped drawing after we reached the first invisible
substitution, the subsequent kinds weren't drawn even if they should
have been.
Add configuration options to specify:
- characters to substitute and their substitution;
- whether to substitute at the beginning, middle or end of the line;
- the color of the substitution;
- the color for the beginning, middle or end;
- the minimum number of white space to show in the middle.
