Subject: [PATCH] gc: use 's' type character for fscanf

The ISO C standard states that using a field width together with the 'c'
type character will read the exact amount specified; if that amount of
bytes is not available, a match error occurs.

This patch allows the t6500 test to pass on the musl libc, and `git gc`
to behave correctly on systems utilising musl.
