It needs to be removed, have an octothorpe prepended, or have an or-ed test prepended. (or something else)

Bonus points for a comment that it's needed for waf versions that ignore GNU dirs.

- - tar -C /tmp/docbot-local/share/doc/ntpsec/ -cf - .|tar -C public/latest/ -xf -
+ - \[ -d public/latest \] || tar -C /tmp/docbot-local/share/doc/ntpsec/ -cf - .|tar -C public/latest/ -xf - # tar to work around waf ignoring GNU dirs
