    Check for empty before isspace in UString::chomp() (Closes: #574214)
    
    	* src/common/nmv-ustring.cc: in cases where a string is all whitespace, an
    	  out-of-range exception was being thrown, because we were checking for
    	  isspace before we were checking that the string was non-empty.  I switched
    	  the order of these comparisons so now we never examine whether the first
    	  character of an empty string is a space.  At the same time I switched from
    	  using size() to using !empty() since theoretically that should be slightly
    	  more efficient.
