Campbell Barton 4b859e91cb bugfix/workaround [#25629] Add torus with autmatic edit mode duplicates mesh after >Aling to View.
adding meshes in C does:
 Add Empty Mesh -> Enter Editmode -> Create Mesh

while python does:
 Add Generated Mesh -> Enter Editmode


problem with this is there is no empty undo state for undo-redo to use so it always gave a duplicate mesh on redo-ing.
workaround by adding an empty mesh, do an undo push, and join the generated mesh into the empty one.

this would be fixed if undo stack spanned modes.
