no way to get symbolic references

[rogpeppe]

It would be nice to have some mechanism for resolving symbolic ref names such as "HEAD" or "origin".

AFAICS the only way currently is to open the relevant files in git to find the commit numbers.

But perhaps I've missed something and there is. If so, perhaps better docs might help.

Ideally it would be great to have a function that could resolve all of the various syntax described in gitrevisions(7).
