to clarify:

I find it odd that {beginning,end}-of-buffer-or-history jumps to the 
beginning/end of the history and not to the beginning/end of the line
if called on a single-line buffer

Jumping to the beginning/end of a line in a multi-line buffer is just an extra 
my function does, and not something I think {beginning,end}-of-buffer-or-history
should do (it's name does not imply any such functionality :)
