Whitespace symbols in STEP lines

[claimred]

Is there a specific reason to put whitespace after the equals sign (#23=_IFCOLUMN)? For example https://github.com/ifcquery/ifcplusplus/blob/master/IfcPlusPlus/src/ifcpp/IFC4/lib/IfcColumn.cpp#L65 (every ::getStepLine function works like that)

Not writing spaces could easily save a hundred kilobytes on large ifc projects. Not that much one could argue, but everything matters in large projects.
