Issue overview

The attached Window5DataFile_ExtraBlankLines.dat (generated by Berkeley Lab WINDOW 7) causes an error when running 1ZoneUncontrolled_Window5.idf.

  ** Severe ** No match on WINDOW5 data file for Construction=EXAMPLE B, or error in data file.
  **  ~~~  ** ...Looking on file=Window5DataFile_ExtraBlankLines.dat

The Window5 data file parser assumes line counts based on the "Window5 Data File for EnergyPlus" line, so the extra blank line causes EnergyPlus to fail to find the window name "Example B".

This defect is likely a one-off as it is unlikely any other applications are generating WINDOW5 data files with extra blank lines in random places. The broader issue is that the parsing logic doesn't handle extra whitespace in general and should be rewritten. I will open a separate enhancement issue to address this. #11194
