I spent some time investigating the difference of vim test results from
different editors. It turns out the value of TERM can affect the test
results in a deterministic way: when TERM=xterm-256color all tests pass,
when TERM=linux one test fails, and when TERM=vt100 20+ tests fail.
As we are redirecting the output to a file, the actual type of the
terminal does not matter and we can just specify a value known to work.
It does no good: normally we have -v for chown so once it no longer has
an effect we can know, but in this case these chown commands will never
have no effect. And a huge amount of output with -v wastes the server
storage and bandwidth (for both the server and the people reading the
build logs).
