range-diff: avoid compiler warning when char is unsigned
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.
