 not documented in Emacs manual

$ 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

As a general comment, the manual does not try to exhaustively list all options.
I am not a dabbrev user, so have no idea how important this one is.

Unfortunately I don't use dabbrev either.  But I can see that no one has
replied here in five years, which is perhaps some kind of indication.

Does anyone else have an opinion here?

Best regards,

No one voiced an opinion within 7 weeks, so I'm closing this bug now.
