I also use Gentoo.

xterm-256 wasn't in portage a couple months ago, so your terminal has
certainly changed in the last few months. Using all combinations of
vim-7.2.{182,411} and xterm-{223,256}, though, I see the undesired
behavior. It looks like older xterms (including 243, which was what I
had installed when I started exploring this) have a USE-flag called
'paste64', which apparently adds the --enable-paste64 compile flag.

My guess is that --enable-paste64 (which is no longer in the ebuild) is
essentially built-in at this point.

Upgrading back to xterm-256 and adding the line:
UXTerm*allowWindowOps: true
to my ~/.Xdefaults file solved the problem[1]. IIUC, this enables
'bracketed paste' mode[2] (possibly other things?), but may have
security implications[1b].

[1] discovered via these lines in the ebuild:
if use paste64 ; then
elog "bracketed paste mode requires the allowWindowOps resource to be true"
elog "which is false by default for security reasons (see bug #91453)."
elog "To be able to use it add 'allowWindowOps: true' to your resources"
fi
