ll-merge: make callers responsible for showing warnings
Since some callers may want to send warning messages to somewhere other than stdout/stderr, stop printing "warning: Cannot merge binary files" from ll-merge and instead modify the return status of ll_merge() to indicate when a merge of binary files has occurred. Message printing probably does not belong in a "low-level merge" anyway. This commit continues printing the message as-is, just from the callers instead of within ll_merge(). Future changes will start handling the message differently in the merge-ort codepath. There was one special case here: the callers in rerere.c do NOT check for and print such a message; since those code paths explicitly skip over binary files, there is no reason to check for a return status of LL_MERGE_BINARY_CONFLICT or print the related message. Note that my methodology included first modifying ll_merge() to return a struct, so that the compiler would catch all the callers for me and ensure I had modified all of them. After modifying all of them, I then changed the struct to an enum. Signed-off-by: Elijah Newren <newren@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
