`git describe` will match the latest tags, regardless of what it looks
like. We can make this a little safer by adding a `--match` flag to
match tags that look like version tags. This allows the maintainers of
this repo to more safely add other types of tags if they so wish,
without causing people to install or upgrade to those versions.
I recently ran the upgrade instructions and I ended up with the version
I was already on. This happened because `git describe` describes a
commit using the most recent tag reachable from it. Since I already had
a tag checked out, it was describing the tag I had already checked out.
Thankfully, `git describe` accepts an optional commit-ish, which it will
use instead of what we have currently checked out. Testing this in my
terminal now gives me the latest tag on origin, which is what I am
interested in when updating to the latest version.
~/.nvm ❯❯❯ git describe --abbrev=0 --tags
v0.30.1
~/.nvm ❯❯❯ git describe --abbrev=0 --tags origin
v0.31.3
I also added it to the manual install instructions for consistency and
extra safety.
