bug#23287: 24.5; git pull in eshell works incorrectly (with servo repository)

[Sum Proxy <sum.proxy@gmail.com>]

Clone servo’s repository https://github.com/servo/servo.git, make a git pull in eshell
and you should see how the last line blinks (as if the newline is alternately added
and removed from shell output). This doesn’t look like proper behavior.
