I'm hesitant to add more command-line option letters, otherwise we
might end up with a BUGS section in the manpage like in indent(1):

BUGS
     The indent utility has even more switches than ls(1).

One possibility would be to extend the -U ("update") option: rather
than only allowing for read ("r") and write ("w") operations, it could
also allow for erase ("e") operations for the memory region specified:

avrdude ... -U application:e:-:n

The third (file) argument is not needed there (I just indicated this
by a file format flag "n", for "nil"), so it could also be abused to
indicate a page to erase:

avrdude ... -U application:e:0x100:m

Opinions?
