Execute command from git configuration

Question

On macOS, the tool ghi (GitHub Issues on the command line) adds the following to ~/.gitconfig:

[ghi]
    token = !security find-internet-password -a username -s github.com -l 'ghi token' -w

It is my understanding that by starting with a !, it means that is a shell command. And indeed it is, as executing it returns the correct authentication token (stored in the macOS Keychain). But running git config --get ghi.token returns the command itself (with !), instead of its result, which was what I was expecting because it seems that ghi would use that to retrieve the key.

What is the git command, if any, to return the result of the command, instead of the command itself?

There is no such command; ghi reads the configuration value, strips the '!' and executes the result:

    value = ENV[var] || `git config #{flags} #{key}`
    value = `#{value[1..-1]}` if value.start_with? '!'

see ghi repository

git uses ! at some places the mark configuration values as programs instead of plain value; but there is not automatic evaluation behind.
