Fix the $pwd tests

Browse Source 
Not sure what happened but my fix for issue #1120 resulted in the core
unit test module not being executed due to a bogus "// +build wtf"
comment. Apparently I was experimenting with "+build" directives and
forgot to remove that line. This also improves the test coverage of the
$pwd code from 44% to 100%.
