I have searched twice now and explored heavily and I concede. I can't find a working answer, to a simple dang problem! :(
Problem
gitk comments on my Mac are not word wrapped and overflow off the screen
Example Illustration
The bottom left window has the commit message overflow out the window ('On add_nscoding: this...')
Question
How do you enable word-wrap in the commit description & comment window on a Mac?
Potential Solution
'wrapcomment' is described of ~/.gitk here - http://marc.info/?l=git&m=114770603010712&w=2. But I could not find where this is!
