I'm not sure what you're doing that's different to everyone else --- it
must involve repeating the last character to go to the mark, so maybe
you've got vi-goto-mark bound to a letter --- but I've never understood
what the code you've modified is actually for, since mark 26 never gets
set.  It's probably best just to remove it.
