[tor-commits] [tor/master] Make check-spaces part of the standard "make check" process

[nickm@xxxxxxxxxxxxxx]

commit 3c04c8317fc98aa64f9be18042a7255842e951c0
Author: Nick Mathewson <nickm@xxxxxxxxxxxxxx>
Date:   Tue Sep 19 10:10:38 2017 -0400

    Make check-spaces part of the standard "make check" process
    
    To do this, we had to make sure it passes when the changes directory
    is empty.  I also tried to improve the quality of the output, and
    fix some false-positive cases.  Let's see how this goes!
    
    Closes ticket 23564.
