extended registers: associate more info with a register

[mqudsi]

This might be a bit of a stretch, but would you consider making available certain information about the buffer the contents of a register were copied from, so that it may be retrieved at the time the buffer contents are pasted?

Use case: copy text from buffer a and paste it into new buffer b, and since there is no ft in buffer b, deduce ft from that of buffer a and apply it to buffer b?

I can understand if it's just not happening :)

Cheers!

Makes sense, but a low-cost first step which could enable more applications, would be register events, e.g. RegisterSetPost, RegisterGetPost.
