Patch to the docstring of `set-mark-command'

[Emilio Lopes]

The variable `set-mark-command-repeat-pop' was recently 
introduced, but the docstring of `set-mark-command' was not 
updated.  This patch fixes this.  The Info documentation was 
already updated.   2006-01-07  Emilio C. Lopes  <address@hidden>

	* simple.el (set-mark-command): mention variable 
	`set-mark-command-repeat-pop' in the docstring.
