A slightly cleaner strategy would be to add a separate header file, say,
`progress-internal.h` or `internal/progress.h` to declare the variables
and the function.

I guess at some stage we really need to define a proper API of libgit.a.
Just because we refuse to declare such an API doesn't mean that people
don't use libgit.a in that way (e.g. cgit, cinnabar). We might just as
well face reality and split up `cache.h` and put the API part into header
files in a subdirectory `include/`.

Ciao,
