This command loads all formulae and dumps an HTML profile report to
stdout. So e.g. `brew profile >/tmp/report.html`

Exposing this as "to_a" was a mistake, versions are not arrays and it
causes incorrect behavior when splatted or using Kernel#Array(). Use the
more correct name "tokens" instead.

Pinned formulae which were pinned at a previous version but then upgraded
would not be listed by `brew list --pinned`. This is due to the good old
"File.exist? thinks broken symlinks don't exist" gotcha, so the test in
the select block in list_pinned has been changed to check if the pin file
exists _or_ is a symlink.

Also complete --devel and the formula's install options.
