I realise you're very busy, and this isn't urgent ...
Would it be practical to implement some forum formatting like the Arduino forum's 'code' blocks?
Key properties (for me) are:
1. The post contains a limited height window, so a very long piece of code doesn't consume a lot of height on a page
2. Indents and layout like line breaks are preserved
3. C escape sequences are preserved.
I've had some problems, as have others, with backslash zero being consumed (I try to write it here in backquotes and it won't work without a space'\ 0'
)
