ansi background color goes over the tail of the next line

[GoogleCodeExporter]

if the line is wrapped in the middle of a highlighted word
then background "flows down" to the end of the next line
see screenshot attached

test command
perl -e '$x="1234567890"; $xBg="\e[41m$x\e[0m"; print "\n\n---ok---\n$x $x $xBg 
$x $x $x"; print "\n\n---bug---\n$x $x $x $x $xBg $x\n\n"'

winxp
cygwin
mintty 1.1.3

and also I've found that background on multiple lines looks different depending 
on scrollbar

Many other terminals exhibit the same effect, including xterm, rxvt-unicode, 
gnome-terminal.
Not necessarily an excuse, but a common point against wrapping and scrolling 
character attributes - applications should avoid that.
