Hmmm... good question.
By the same token, the mirror image of "info addr" is
"info symbol". It takes an address, and finds a symbol
that matches. In some corner cases, there might be more
than one symbol at the same address, but I assume info
symbol will only show the first one found. Maybe that
should be addressed too (no pun intended).
