This seems to be unreachable from first introduction at r21286.
In ERB implementation, #empty? is only called for each member of return value of String#scan, and ERB::Compiler::PercentLine is never returned from String#scan.
Also, in ERB::Compiler#compile, as it's yielded only when stag is nil, methods called to ERB::Compiler::PercentLine object yielded from ERB::Compiler::TrimScanner#scan are only: #nil?, #==, to_s.
Thus ERB::Compiler::PercentLine#empty? is never used.
