Pacman doesn't really have a way of looking at an installed package
and knowing that it's been modified from the default repo package (as
far as I know ...).  Absent a new patch to add such functionality,
Karol's suggestion of IgnorePkg is the best idea and also provides the
warning you seek when performing a full update, in the form of

warning: package_foo: ignoring package upgrade (1.0.0-1 => 1.1.0-1)

This warning lets you know that something you're ignoring has been
updated, and you should take steps based on the reason you ignored it;
IgnorePkg does not interfere with a 'pacman -U' operation, and if
specifically told to install an ignored package from repos via 'pacman
-S package_foo' will ask for confirmation.
