Re: [PATCH v2] travis-ci: fix Perforce install on macOS

Lars Schneider [off-list ref] writes:

The `perforce` and `perforce-server` package were moved from brew [1][2]
to cask [3]. Teach TravisCI the new location.

Perforce updates their binaries without version bumps. That made the
brew install (legitimately!) fail due to checksum mismatches. The
workaround is not necessary anymore as Cask [4] allows to disable the
checksum test for individual formulas.

Hi,

this small update removes one more unnecessary line and makes the
formula name lower case (no functional reason - just looks better ;-).

@Junio: Do you prefer such a v2 as "--in-reply-to" to v1 or as separate
        thread? What eases your workflow?

It does not make that much of a difference if the second one comes
within a few days since the first one but in general it probably
would help if the follow-up is threaded _and_ made it clear upfront
that if somebody is reading v2 then v1 can be ignored ;-).

Thanks.
