cache.h: clarify documentation for git_path, et al
The comment above these functions actually describes sha1_file_name, and comes from the very first revision of git. Commit723c31f
(Add "git_path()" and "head_ref()" helper functions., 2005-07-05) added git_path, pushing the comment away from the function it describes; later commits added more functions in this block. Let's fix the comment to describe these related functions in more detail. Let's also make sure to point out their safer alternatives (and move those alternatives below, which makes more sense when reading the file). Note that we do not need to move the existing comment to sha1_file_name. Commitd40d535
(sha1_file.c: document a bunch of functions defined in the file, 2014-02-21) already added a much more descriptive comment to it. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
