Side note: They tend to do "looping over all the paths, see with ce_path_match() if the path matches, and do something with that path if it does". They do not do a separate useless loop that is only for checking if all the pathspec elements match, like the loop in this patch does. In a sense, not making this into a helper function is the right thing to do. It would avoid encouraging this anti-pattern of adding a separate and otherwise useless loop. We must already be using pathspec elements to decide to do the "include" addition among all paths that we know about in some loop separately, no? Isn't that what the call to add_files_to_cache() we see in the post-context doing? Shouldn't that loop (probably the one in diff-lib.c:run_diff_files(), that calls ce_path_match() for each and every path we know about) be the one who needs to learn to optionally collect the ps_matched information in addition to what it is already doing? Thanks.
