What's wrong with '\<do_exit\>'?
Christ people, you both make it so complicated.
If you want to search for 'do_exit', just do
git grep -w do_exit
where that '-w' does exactly that "word boundary" thing.
I thought everybody knew about this, because it's such a common thing to do - checking my shell history, more than a third of my "git grep" uses use '-w', exactly because it's very convenient for identifier lookup
But yes, in more complex cases where you have other parts to the pattern (ie you're not looking *just* for a single word), by all means use '\<' and/or '\>'.
