bug#26712: other-window/frame versions of find-library

FWIW, I proposed this in March 2007 ("Please add
`find-library-other-window'")
http://lists.gnu.org/archive/html/emacs-devel/2007-03/msg01073.html

I was told not to propose new features at that time.

I proposed it again in June 2007 ("how about a
find-library-other-window command?",
http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg01306.html).

That thread was hijacked to a discussion about simulating
all `-other-*' commands automatically (still one of Stefan's
quests, I believe).

I more than once tried to bring the discussion back on topic.
http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg01319.html

["This is all beginning to sound a bit complex. Perhaps worth
exploring, but, in the meantime, could we at least add
`find-library-other-window'? ;-)"]

RMS, at least, responded favorably, asking for a patch.

Juri complained that "polluting the namespace is not a good
thing.  There are too many commands that display a new buffer,
and don't have the duplicate name with the `-other-window'
suffix, and adding more redundant commands will increase the mess."

I sent the patch anyway.
http://lists.gnu.org/archive/html/emacs-devel/2007-06/msg01428.html

RMS agreed to it and asked that someone install it.

Juri complained that the code was repetitive for the 3
commands.  It was never installed.

Glad to see it finally added to Emacs.  I've been using it
for 10 years.  I bind it to `C-x 4 l'.  (I never use plain
`find-library'.)
