As we are not doing anything dynamic to the help text, I think dropping "again" in [1/2] would make sense. Will queue. Thanks.

The interactive-patch is a sequential process where, on each step, we print one hunk from a patch and then ask the user how to proceed. There is a possibility of repeating a step, for example if the user enters a non-applicable option, i.e: "s" $ git add -p diff --git a/add-patch.c b/add-patch.c index 52be1ddb15..8fb75e82e2 100644 --- a/add-patch.c +++ b/add-patch.c @@ -1394,7 +1394,7 @@ N_("j - leave this hunk undecided, see next undecided hunk\n" static int patch_update_file(struct add_p_state *s, struct file_diff *file_diff) { - size_t hunk_index = 0; + size_t hunk_index = 0, prev_hunk_index = -1; ssize_t i, undecided_previous, undecided_next; struct hunk *hunk; char ch; (1/4) Stage this hunk [y,n,q,a,d,j,J,g,/,e,p,?]? s Sorry, cannot split this hunk @@ -1394,7 +1394,7 @@ N_("j - leave this hunk undecided, see next undecided hunk\n" static int patch_update_file(struct add_p_state *s, struct file_diff *file_diff) { - size_t hunk_index = 0; + size_t hunk_index = 0, prev_hunk_index = -1; ssize_t i, undecided_previous, undecided_next; struct hunk *hunk; char ch; (1/4) Stage this hunk [y,n,q,a,d,j,J,g,/,e,p,?]? ... or an invalid option, i.e: "U" $ git add -p diff --git a/add-patch.c b/add-patch.c index 52be1ddb15..8fb75e82e2 100644 --- a/add-patch.c +++ b/add-patch.c @@ -1394,7 +1394,7 @@ N_("j - leave this hunk undecided, see next undecided hunk\n" static int patch_update_file(struct add_p_state *s, struct file_diff *file_diff) { - size_t hunk_index = 0; + size_t hunk_index = 0, prev_hunk_index = -1; ssize_t i, undecided_previous, undecided_next; struct hunk *hunk; char ch; (1/4) Stage this hunk [y,n,q,a,d,j,J,g,/,e,p,?]?

Printing the chunk again followed by the question can be confusing as the user has to pay special attention to notice that the same chunk is being reconsidered. It can also be problematic if the chunk is longer than one screen height because the result of the previous iteration is lost off the screen (the help guide in the previous example). To avoid such problems, stop printing the chunk if the iteration does not advance to a different chunk.
