If you want ‘git diff | pager’ to work like that, you’re out of luck. There is no way for the pager to communicate with git or the shell to rerun the command; the pager doesn’t even know what program is on the writing side of its stdin pipe. You would need something like ‘pager --command "git diff"’, where the pager invokes a command producing output. I do agree that it would be nice.
