[FR] add aliased command to `$desc`

[oldfatcrab]

Is your feature request related to a problem? Please describe. I'm always frustrated when using the git alias, there are too many g... alias I can choose (i.e. alias gpsup="git push --set-upstream origin $(git_current_branch)").

Describe the solution you'd like If the aliased command can be written into $desc that will be great. (and so on for shell function and parameter)

Describe alternatives you've considered Or some documentation on how to customize $desc field will be also good.
