Distinguish between regional undo and undo to the beginning in undo-equiv-table |

Currently if I undo to the beginning of the pending-undo-list, buffer-undo-list
is mapped to t in undo-equiv-table. Meanwhile, if the undo is undo-in-region,
the buffer-undo-list is also mapped to t in undo-equiv-table.
That means my package that constructs an undo tree from buffer-undo-list cannot
distinguish the two and thus cannot work incorrectly. Is it ok to map one type
of undo to something other than t? Maybe a symbol 'undo-in-region? Would that
break anything? Or maybe we can create another hash table to mark
undo-in-region undos.
I can explain how does my package use undo-equiv-table if needed.
