Subject: bug#16822: 24.3.50; show-paren-mode adds confusion to active region
Date: Thu, 20 Feb 2014 15:40:51 +0800	[thread overview]
Message-ID: <874n3utenw.fsf@gentoo.i-did-not-set--mail-host-address--so-tickle-me> (raw)


When show-paren-mode is on, it adds confusion to the active
region. Suppose I have some text which is (hello),

1. I set the region to (hello and place the cursor on the left paren.
2. I set the region to (hello) and place the cursor on the left paren.

Note that in Case 1, the right paren is not part of the region while in
Case 2 it is. In the two cases above, I get exactly the same color on
the screen, then how can I distinguish between these two different
cases?

Compared to the more rational behavior of Emacs 24.3, I think the paren
which is part of the region should have the same color with the region
while the paren which is not part of the region can has matching paren
color. In this way, the user can tell which part is selected and which
part is not.
