This patch makes erlc print column numbers when compiling .erl files through a
new compile option, "column":

	$ cat foo.erl 
	-module(foo).
	foo(X) -> bar.
	$ bin/erlc foo.erl
	foo.erl:2: Warning: function foo/1 is unused
	foo.erl:2: Warning: variable 'X' is unused
	$ bin/erlc +column foo.erl
	foo.erl:2:1: Warning: function foo/1 is unused
	foo.erl:2:5: Warning: variable 'X' is unused
