WISH: Visualize/highlight different whitespace symbols

[HenrikBengtsson]

It is sometimes useful to be able to see the difference between various whitespace symbols, e.g. space ( ), TAB (\t), CR (\r), LF (\n), BACKSPACE (\b), ... This can be particularly helpful when for instance troubleshooting a tab-delimited file (which e.g. uses spaces instead of TABs).

Visualization of whitespace could be done by using different background colors, e.g. (ignoring themes)

• space - default background
• TAB - red
• BACKSPACE - yellow
• CR - magenta
• LF - blue

@HenrikBengtsson Thank you for your feedback. I was hesitant to add this in the past, but I have thought about this again and came up with this idea/implementation: #395. It's not quite what you requested, but I would love to hear your feedback.
