The breakindent
feature is the greatest thing ever, but it's in 7.4.338. The latest version in the Ubuntu repos is just 7.4, I think. I notice Arch has a package for it, but I can't seem to find one for Ubuntu yet. I'm hopeless with compiling things, otherwise I'd compile it myself.
There is the pi-rho/dev PPA, which has up-to-date vim packages.
(The current default version for trusty is 8.0.0134.)
The PPA is available for currently supported releases.
Vim 8.0 (just released, 2016-09-12) can be installed from a PPA in Ubuntu 14.04 and 16.04.
Today I found this one
It uses the new dailybuild function from launchpad to automatically grab the upstream source and build if there has been a change. So nearly no maintenance needed from ubuntu side.
