Subject: bug#22303: 24.5; toggle-truncate-lines not mentioned in docstring for truncate-lines nor in elisp manual
Date: Mon, 4 Jan 2016 10:30:17 +0100

In general, changing the value of `truncate-lines' should be done via 
`toggle-truncate-lines' not by `(setq truncate-lines ..)'

However the documentation string for `truncate-lines' does not mention 
the existence of `toggle-truncate-lines', nor is it mentioned in the
elisp manual (section "37.3 Truncation").

It seems that modifying `truncate-lines' with just `(setq ..)' may 
suffer from redisplay problems, see 
http://emacs.stackexchange.com/questions/19228 for a way to trip the 
problem from emacs -Q.
