[O] suggestion: M-m should move point to first word on line

[Meng Weng Wong]

Ordinarily, M-m is bound to (back-to-indentation) – move point to the first 
non-whitespace character on the line. It differs from C-a.

Might it make sense for org-mode to override M-m?

Move the point to the first "user" word on the line, to the first 
non-asterisk/whitespace/dash/TODO character on the line.
