I don't think chop() is an operation that's done often enough for
either of the things above to be a problem.

Yes, but chop()'s original purpose was what chomp() is now used for.
I doubt Larry would really have put in a function to remove the last
char in a string just to have a function that removes the last char in
a string.  It was the chomp()-like itch I think he was trying to
scratch.
