jamstream completions

Print shell completions for jamstream.

Usage: jamstream completions <SHELL>

SHELL is one of bash, zsh, fish, powershell, or elvish.

Installed through Homebrew, completions are set up for you. Installed any other way, add one line:

# zsh (~/.zshrc)
$ source <(jamstream completions zsh)

# bash (~/.bashrc)
$ source <(jamstream completions bash)

# fish
$ jamstream completions fish > ~/.config/fish/completions/jamstream.fish

# PowerShell ($PROFILE)
jamstream completions powershell | Out-String | Invoke-Expression

PowerShell only runs $PROFILE scripts under an execution policy other than Restricted, the default; Set-ExecutionPolicy -Scope CurrentUser RemoteSigned is enough.
