Understandable. We do this all the time in Git for Windows. Our config
entry has this form:

		sslCAinfo = /ssl/certs/ca-bundle.crt

and in the RUNTIME_PREFIX mode, this will be made relative to the runtime
prefix. It is my understanding that bf9acba (http: treat config options
sslCAPath and sslCAInfo as paths, 2015-11-23) makes this work.

I think if you simply delete `<prefix>`, it will start working.
