refactor(grid): reimplement 'rightleft' as a post-processing step

Browse Source 
problem: checks for wp->w_p_rl are all over the place, making simple
things like "advance column one cell" incredibly complicated.

solution: always fill linebuf_char[] using an incrementing counter,
and then mirror the buffer as a post-processing step

This was "easier" that I first feared, because the stupid but simple
workaround for things like keeping linenumbers still left-right,
e.g. "mirror them and them mirror them once more" is more or less
what vim did already. So let's just keep doing that.
