Maybe think about it this way: The only difference between git's
globbing and the default shell globbing is that the '/' in a path has a
special meaning. The shells expansion stops at a '/' but git does not.

So with *.c the shell matches: blabla.c, blub.c, ...  but not
subdir/bla.c, subdir/blub.c, ... since it only considers files in the
current directory. A little different for Makefile* that will also match
Makefile.bla, Makefile/bla or Makefile_bla/blub in shell but not
subdir/Makefile or bla.Makefile. Basically anything directly in *this*
directory that *starts* with 'Makefile'.

Git on the other hand does not consider '/' to be special. So *.c
matches all of the path above: bla.c, blub.c, subdir/bla.c,
subdir/blub.c. Basically any file below the current directory with a
path that ends in '.c'. With Makefile* it is the opposite: Every file
below the current directory that *starts* with 'Makefile'. So
Makefile.bla, Makefile/bla, ... but also not subdir/Makefile or
bla.Makefile.

Maybe that helps...

Cheers Heiko
