I just tested on a mostly freshly rebooted system, and the only
such program to interfere is klipper, which is not started.

I tested it like this:

tglase@tglase:~ $ echo pri | xsel -p
tglase@tglase:~ $ echo sec | xsel -s
tglase@tglase:~ $ echo cli | xsel -b

Then I hit “info gcc”, pressed ‘/’.
Simple middle-click does nothing.
Shift-middle-click inserts “cli” and Enter (I should have
used “echo -n” maybe).

xsel(1) sets *only* the selection chosen on the command line.
Changing the order of the commands (reversing) is indifferent.

So, yes, I am 100% sure that Shift-Middleclick in info(1)
currently inserts the CLIPBOARD and not the PRIMARY selection,
greatly inconveniencing classical Unix text tool users.

Note: all tests were run in screen inside xterm; relevant
$TERM variables are “xterm” and “screen” (not “screen.xterm”),
though that only matters for info(1) as xterm itself (and
screen, obviously) don’t set the selections in this example.
