Minor optimization to tree entry validity check

This checks for a leading '.' before looking for the invalid
tree entry names.  Even on pretty high levels of optimization,
this seems to make a measurable improvement.

I accidentally used && in the check initially instead of || and
while debugging ended up improving the error reporting of issues
with adding tree entries.  I thought I'd leave those changes, too.
