[Wine] Regression test - bad rev input

[Col]

Hi,
I have been trying to do a regression test between 1.1.10 and 1.1.12, as there seems to be a number of problems with the installation of the Macromedia suite (Dreamweaver, Fireworks, Flash).
I think I have ccache installed.
I think I have git OK.
I run git bisect start ok,
Then when I run git bisect good wine 1.1.10, I get:
Bad rev input: wine 1.1.10.

What am I doing wrong?
