Verify that rebuilds do not occur when SConsignFile(None) is used to
put a .sconsign file in each directory and we subdvide the dependency
tree with subsidiary *SConstruct* files in various subdirectories.
This depends on using content signatures for evaluation of intermediate
Nodes. We used to configure this explicitly using
TargetSignatures('content'), but we now rely on the default behavior
being the equivalent of Decider('content').

# scripts directly, not by feeding them to the Python executable.
# That is, we chmod 0755 and us a "#!/usr/bin/env python" first
# line for POSIX systems, and add .PY to the %PATHEXT% variable on
# Windows. If we didn't do this, then running this script with
# suitable prileveges would create a .sconsign file in the directory
# where the Python executable lives. This can happen out of the
# box on Mac OS X, with the result that the .sconsign statefulness
# can mess up other tests.
