A “specified space” of width equal to the difference of the pixel
widths of the line numbers area and the current line number? If Emacs
does not have a notion of right-aligned text output, that is. Which
would be surprising in an application that supports RTL, but what do I
know.

I am assuming that the motivation for aligning line numbers is the
same as for other columns of numeric data: putting digits of the same
order of magnitude under each other (as long as the font is
fixed-width wrt digits; otherwise, add “roughly”). This does not
change for Arabic and Hebrew, where, as far as I know, decimal numbers
are still written with the most significant digit to the left. So it
makes sense to me to right-align these too, although I’m not closely
acquainted with R2L typographic conventions.
