The only argument I hav= e heard for this is because 'left shifting' a block of text 'lo= oks bad'.

However, the solution looks even worse.

If a programmer doesn't like the left shift, put the tex= t in a file of it's own or put it in DATA.

Doe= s anyone else agree? Does anyone have a better reason to spend time on this= ?

That's essentially what #tabto does. It keeps relative spacing ba= sed
on the first line and optionally adds `n` spaces of indention.

The #margin method was written to emulate literal syntax %L. It not that anyone wants to see the '|' (or whatever character one chooses= ),
rather it is that it allows for a literal representation of the
multi-line string, whitespace and all.
