Yeah, I also found it somewhat confusing to have these two headers
that look quite similar to each other at the top-level of the tree.
What's the "conditional" part between the two headers? Is it just
whether the header for underlying library is included? I wonder if
it's just the matter of adjusting "hash.h" to read like this
...
#if defined(DC_SHA1_EXTERNAL)
-#include "sha1dc_git_ext.h"
+#include <sha1dc/sha1.h>
+#include "sha1dc_git.h"
#elif defined(DC_SHA1_SUBMODULE)
...
or are there heavier tweaks needed that won't be solved by continuing
along the same line? As _ext.h variant is included only at this place,
if we can do with minimum tweaks around here without introducing it,
it may be ideal, I would think.
Thanks.
