Standard less interprets ^H by moving the cursor to the left, characters
overstruck this way (x^Hx) are bold. I have made runtime/syntax/pager.vim which
mimics this, and updated less.vim to use it when the input is stdin. I'm not
sure if everything is done the way it should be, but the patch works and it's
only a few lines. Plus, we get nice yellow-and-white instead of stupid
monochrome :)
This among others fixes man pages and the python repl help() command.
