Remove deprecation warning about 'display.height' option.
Hi,

See the related issue at https://github.com/pydata/pandas/issues/4026

Best regards,
Damien

this is ok, but for 0.12 (I know could be done here, but trying to avoid API changes),

also can you hookup travis?
 Fine for me for 0.12. I see "Milestone 0.13", close to the pull-request title, was it updated?

"hookup Travis": did you mean that I should activate the Travis hook for my pandas repo ? I sign in. See https://travis-ci.org/garaud/pandas

I'm a "Travis-CI" newbie ;-) I don't know how I can tell to Travis to build this pull-request or this branch, i.e. "display_format". Should I be more patient? I quickly read the doc but I don't find a clearly answer.
 0.11.1 was just changed to. 0.12 (as its now a major release
so this will be in next one

look at contributing in the main pandas dir
shows how to hookup up to Travis; u have to hook up
turn it on then push again

lmk if u need help
 OK. Looks fine See https://travis-ci.org/garaud/pandas/builds/8501905

Note that when I pushed a few hours ago, I saw that the latest commit of the branch master wasn't passed. It deals with the pull request about color_map.

See you.
Damien
 yeh....some intermittent network failures on a couple of unreleated tests
 #4391 should silence this, without reintroducing (the useless) height options.
Thanks @garaud for the fix, I thought it best to solve this that way.

Note that 2.7 silences deprecationwarnings by default, which is why I (and I suspect
the other developers) didn't need to scratch this itch ourselves earlier.

might do well for devs/travis to turn this on to get a better feel for latent issues. (cc @cpcloud)
 yes i test on 2.7 ... so i don't see these very often and when i do i ignore them

@y-p good idea to turn on `DeprecationWarning` reporting for testing.
