Grumble.  Incoming "name" is already (const char*), isn't it?
I'd cast only the sha1 side and apply.

However, I think -Wcast-qual is a pretty useless option.  

The nastiest one, if you care, is exec_cmd.c::execv_git_cmd()
where we never muck with "const char **argv" ourselves, but we
have to call execve(), which takes (char**) as its second
parameter.  We cast away constness for that call; otherwise you
would then get prototype mismatch.
