D54: Added a filepath attribute to the read_homefile operator.
This attribute allows to open a blend file as an alternative start-up file. The attribute is only available from python. This is an example call: bpy.ops.wm.read_homefile(filepath='path/to/a/file.blend') This patch also changes readfile.c to ensure that unintentionally stored cursor states are not imported from the loaded file.
