This way, the information is still encoded on the same line, but it's a
comment, so if a newcomer copy/pastes that command line, it will really
work.  

Ok, I see your point.

I did this way since the qemu cmd line can be on several lines (see
board/qemu/arm-vexpress-tz/readme.txt).

Do we require that the qemu cmd line must be on one line ?

Is it really because it is on multiple lines that you need this marker?
Not because some readme.txt document several different defconfigs, and
you need to know which qemu command line corresponds to which defconfig
?
