+Subject: [PATCH] range-diff: avoid compiler warning when char is unsigned
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Since 2b15969f61 (range-diff: let '--abbrev' option takes effect,
+2023-02-20), GCC 11.3 on Ubuntu 22.04 on aarch64 warns (and errors
+out if the make variable DEVELOPER is set):
+
+range-diff.c: In function ‘output_pair_header’:
+range-diff.c:388:20: error: comparison is always false due to limited range of data type [-Werror=type-limits]
+  388 |         if (abbrev < 0)
+      |                    ^
+cc1: all warnings being treated as errors
+
+That's because char is unsigned on that platform.  Use int instead, just
+like in struct diff_options, to copy the value faithfully.
