From 1b9fbefbe08ff2bbcbb8a6089867b32fca603eac Mon Sep 17 00:00:00 2001 From: Elijah Newren Date: Sat, 30 Jun 2018 18:24:56 -0700 Subject: index_has_changes(): avoid assuming operating on the_index Modify index_has_changes() to take a struct istate* instead of just operating on the_index. This is only a partial conversion, though, because we call do_diff_cache() which implicitly assumes work is to be done on the_index. Ongoing work is being done elsewhere to do the remainder of the conversion, and thus is not duplicated here. Instead, a simple check is put in place until that work is complete.
