This patch includes missed changes that should have gone in with r256863, but I can't get to svn at lldb.org at the moment (is it down?), so if someone else can, please commit these for me, and update http://reviews.llvm.org/D15593 to include the commit. Thanks!
Intended commit message was:
Apply missed changes from svn r256863 "Add support for "source info" and use it to fix MI's -symbol-list-lines.". Differential Revision: http://reviews.llvm.org/D15593
