When the "header_list" struct member was added in [1] it wasn't made
to free the list using loop added for the adjacent "pattern_list"
member, see [2] for when we started freeing it.
This makes e.g. this command leak-free when run on git.git:
./git -P log -1 --color=always --author=A origin/master
1. 80235ba79ef ("log --author=me --grep=it" should find intersection,
not union, 2010-01-17)
2. b48fb5b6a95 (grep: free expressions and patterns when done.,
2006-09-27)
