Propose update to master config file

Per the documentation: http://docs.saltstack.com/en/latest/ref/configuration/master.html#include-configuration  the include directive is unset by default.  As documented at the top of the master config file: "Values that are commented out but have no space after the comment are defaults that need not be set in the config. If there is a space after the comment that the value is presented as an example and is not the default."  Therefore, I propose adding a space after the comment to clarify that this is an example directive and not the default.
fix the salt.utils.expr_match

here is a new method in version `2014.7.0`, and only one caller `salt.utils.expr_match(keyid, line)` in 'salt.master.check_signing_file`. 
the caller pass keyid(the minion_id) and line(read from the autosign.conf) as sequence, but the method expr_match handles them as wrong seq.
fix it, and test it in my local env
