RFH: gitk equivalent of "git log -p --full-diff file.cpp"

Hello All -

Hopefully I'm just being dense, but there's a useful tortoisesvn feature that (so far) I haven't found in gitk. Blasphemy! Sniveling windoze luser, etc^2.

Anyway what I'm looking for is the gitk equivalent of:

    git log -p --full-diff file.cpp

That is to say: I want to see all commits which touch a given file along with all of the other files changed by that commit.

    gitk -p --full-diff EntryPoints.cpp

doesn't quite do it - it treats the "extra" diffs as part of the commit msg. Anyone got more if a clue than me?

Thanks - Eric

PS - Aside from aliases, am I missing a simpler spelling of the above
     git log command?
