Short channel matching for julia command
Closes #830 This pull request introduces the feature of short channel matching for the Julia command. Users can now launch alpha, beta, LTS, release, and nightly versions by specifying their respective short names: "a" for alpha, "b" for beta, "l" for LTS, "r" for release, and "n" for nightly.
This error message is interesting, but upon reflection seems pretty good. It would be slightly better if the message explicitly mentioned that l expanded to lts.
$ julia +l
`lts` is not installed. Please run `juliaup add lts` to install channel or version.
Would be good to add a test, too
Needs docs
I think I've finally am getting clarity what I'm thinking about this, see https://github.com/JuliaLang/juliaup/issues/830.
I'm closing this for now, as I don't think we will go with this kind of solution.
