change: add ability to reference single functions or variables

[Kamilcuk]

Is your change request related to a problem? Please describe.

Hello. I would want to display a page documenting specific variables and functions of a file, not all.

Describe the solution you'd like

Ideally:

Look at my function:

::: bin/myscript.sh myfunction

This variable is important:

::: bin/myscript.sh myvariable

Describe alternatives you've considered

I have considered no alternatives, or some custom sed scripting.

Additional context

Great project, thank you!

Hi @Kamilcuk, thanks for the feature request! It would be great to support injecting docs for functions only, great suggestion 🙂
