Hrmm.

$ git log --follow arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.c
fatal: ambiguous argument 'arch/i386/kernel/cpu/cpufreq/acpi-cpufreq.c':
unknown revision or path not in the working tree.
Use '--' to separate paths from revisions

Using --follow on the arch/x86 post-merge file gives me even less info
than it does without it :)

Is what I'm seeing above indicative of this bug ? Or something else?  
Adding -p or --stat makes no difference at all.
