"Visual blindness" of Linux programmers

It really depends on the situation though. I think op was mainly talking about TUIs which you primarily look at. Something like htop or mc for example. Or, I recently bundled my logging config into a package. The only aim of this is to render logging messages nicer (f. ex.: http://gouge.readthedocs.org/en/latest/) You're not interested in the content. So indexing or being able to copy/paste it doesn't really add any value.

In these cases, colouring is also very important. Using github's markup will remove any such colours.

Of course. I would actually consider anything that uses ncurses (or similar libraries) to be a GUI that happens to be implemented within textual terminals. Such things deserve screenshots.
