Subject: bug#28774: Master, emacs-26: Can't add text property to built-in function name.
Date: Tue, 10 Oct 2017 07:01:52 -0700 (PDT) [thread overview]

If `format' no longer always copies STR in this context then
its doc should be updated, I think.
This:
Format a string out of a format-string and arguments.
The first argument is a format control string.
The other arguments are substituted into it to make the
result, a string.
suggests that it creates a new string, or at most reuses
the format string (e.g., "%s"), modifying it by substituting
STR for %s in it. If in fact it can sometimes simply return
STR then this should be mentioned explicitly, to avoid confusion.
(And why was this change made? Was it just to save a string
copy?)
This is an incompatible Lisp change, if it is new. In that
case, it should be documented as such.
