[nemiver/follow-fork-mode] Allow pumping just one asm instruction.

[Dodji Seketeli <dodji src gnome org>]

commit 206cd7f7e891a64432b040b9c1ebb905a00a123a
Author: Dodji Seketeli <dodji redhat com>
Date:   Sat Jul 17 18:12:33 2010 +0200

    Allow pumping just one asm instruction.
    
    	* src/persp/dbgperspective/nmv-dbg-perspective.cc
    	(DBGPerspective::disassemble_and_do): Add a new parm to pump addresses
    	tight. I.e. to pump just one instruction.
    	(DBGPerspective::load_file): Likewise. Adjust when calling disassemble_and_do.
