nova/compute/api.py:378:1: W293 blank line contains whitespace

^
    JCR: Trailing whitespace is superfluous.
    FBM: Except when it occurs as part of a blank line (i.e. the line is
         nothing but whitespace). According to Python docs[1] a line with only
         whitespace is considered a blank line, and is to be ignored. However,
         matching a blank line to its indentation level avoids mistakenly
         terminating a multi-line statement (e.g. class declaration) when
         pasting code into the standard Python interpreter.

         [1] http://docs.python.org/reference/lexical_analysis.html#blank-lines

    The warning returned varies on whether the line itself is blank, for easier
    filtering for those who want to indent their blank lines.

    Okay: spam(1)
    W291: spam(1)\s
