[Qgis-developer] QgsProject.instance().writeEntry() with spaces in var name

[Olivier Dalang]

Since https://github.com/qgis/QGIS/pull/469 (quite old) you're supposed to
get a warning message in the console when using invalid keys.

Keys must be valid XML names in order to be properly saved to the file.

To me, being able to use invalid keys in the first place could arguably be
considered as a bug. It would maybe be better to have an exception thrown
in these cases.

Best regards,

Olivier
