Weight Paint (Weight-Transfer) Does not work as documented
Open, NormalPublic

Description

System Information

Blender Version
Broken: 2.78c

Short description of error
Only the active vertex group is copied to the destination mesh.
The manual states "By default this tool copies all vertex groups contained in the selected objects to the target object."

Exact steps for others to reproduce the error
Selecting the source mesh, then shift-selecting the destination mesh, then selecting Weight-Paint, and then pressing Transfer Weights.
I tested this with matching empty groups on the destination, and with no groups on the destination.
It's easy to see that only the source's active group is copied.
There is no way to select multiple or all groups on the source.

Yep, doc would need an update, since one or two releases this tool now uses the more generic Mesh Data Transfer one, which by default only transfers active layer. Note that in the operator redo panel, you can select 'By Name' source layers, which will then transfer all existing ones in the source to the destination mesh.
