Bug in git log

Hello list,

I found a bug in the new builtin git log which I am unable to fix myself.

Inside your git source directory, do:

First bug using old whatchanged script (not builtin version)

$ ./git-whatchanged.sh -- unresolve.c fatal: ambiguous argument 'unresolve.c': unknown revision or filename Use '--' to separate filenames from revisions

$ ./git-whatchanged.sh -- -- unresolve.c [...] gives the expected output

$ git log -- unresolve.c $ git log -- -- unresolve.c $ git whatchanged -- unresolve.c

both give no output.

I checked the argument parsing stage and everything seemed sane (the second double-dash was not necessary anymore)

However, the following works as expected:

$ git log -- git-log.sh

It seems that the problem shows only if there was no commit modifying the asked-for file. unresolve.c is introduced in commit ec167793d84ba7b765e1eb71b0257ce7baca2d26 and removed in the subsequent commit 2bd452d3b9f62ecc3406307cd6a5553856d21ff2 and is never modified.
