I still wonder if this would be clearer if we listed 'tcg' as
an accelerator like all the others, rather than describing it as
a kind of special case in the text above the table. After all, you
can select it with '-accel tcg' the same as any other.

I think the information in the table is correct now.

Sort the list of accelerators alphabetically ?

This change appears to be unrelated ?
