Everyone.

  1. People who download the source code and want to install git in a
     similar way to how distributions do it
  2. Developers who have no idea what's good in contrib/
  3. Distribution packagers who want to know what's good enough to be
     distributed, and don't want to manually copy files (i.e. all
     distribution packagers)

That is not true.

Distributions do not want to decide where to place
`contrib/completion/git-prompt.sh`, they want the git project to decide.

Obviously it has to be under '/usr/share/', preferably
'/usr/share/$project' (i.e. not /usr/share/git-core), but other than
that they do not care.

Sure, that would help, but they still would want an install-contrib target.

A distribution packager that is maintaining 20 packages (or more)
doesn't want to keep track where every single file of her every
single package goes. She just wants to do `make install` and be done
with it. Any package that requires to manually copy some files to the
destination is simply a hassle to maintain.
