What's the syntax for checking out a specific tag on a remote?
This depends on where you stored the tags you obtained from the
remote. By default, "git fetch --tags" would store the tags in
a flat namespace; there is no "remote tag" namespace.
Hence you would say:
git checkout v2.6.19
to get a detached HEAD at v2.6.19, or if you want to start a
branch from there,
git checkout -b my19 v2.6.19
