Naming of ‘append-to-buffer’

[Andreas Röhler]

Docstring mentions substring from old buffer "is inserted into that 
buffer before its point". But the meaning of "append" is a different 
one. IMO the current behavior might be expressed as ‘copy-to-buffer’ or 
‘insert-in-buffer’, as copy-... is taken already. OTOH would appreciate 
to have a reliable append, i.e. insert at the EOB.

Cheers,
Andreas
