Commit a8c8a03 introduces a cvar to toggle the name mangling ("prettification" according to capsadmin).
However, it does not introduce a cvar to toggle the new forced eye/mouth/etc category grouping behavior, which uses blind name matching to assume the intent and location of flexes by their internal string names within the context of valve bipeds. This is a poor idea to force without a toggle to disable it, since most models are not valve bipeds and may have confusingly misgrouped flexes in the editor.
Also, randomly and rather unluckily for me, the anti-mangling and alphabetical sorting introduced in this smelly commit are things I just implemented myself on the very same day, in a different way. Here's another relevant issue discovered from that work: #1438
