[Message part 3 (message/rfc822, inline)]

From: Ihor Radchenko <yantar92 <at> posteo.net>
To: bug-gnu-emacs <at> gnu.org
Subject: 30.0.50; string-pixel-width return value is affected by 'line-prefix

According to the docstring of `string-pixel-width', it "Return the width
of STRING in pixels."

Consider the following:

(string-pixel-width "asd") ;=> 30
(string-pixel-width (propertize "asd" 'line-prefix "123")) ;=> 60

Should the value of 'line-prefix be appended to the string width?

According to https://debbugs.gnu.org/cgi/bugreport.cgi?bug=64696#173,
'line-prefix "does not affect the width of the string itself".
