$ emacs -Q -l dabbrev --eval="(describe-variable
'dabbrev-friend-buffer-function)"
Unless I am mistaken, there is no mention of
dabbrev-friend-buffer-function in the
Emacs manual. This symbol, if bound, should contain a function that
given a buffer
argument will tell if the buffer should be searched while
dabbrev-expand'ing.
Further dabbrev-friend-buffer-function is initially bound to
dabbrev--same-major-mode-p, with the effect that
only buffers with same major mode are searched through. This behaviour,
while often welcome, can be treacherous at times,
and is not documented in the manual.
This may have a connection with bug #17899
