Revision bb84735c80dbae6408b79b56f574ae672d2232d4 authored by René Scharfe on 23 October 2016, 17:57:30 UTC, committed by Junio C Hamano on 26 October 2016, 17:54:11 UTC 
hex: make wraparound of the index into ring-buffer explicit
 
Overflow is defined for unsigned integers, but not for signed ones.

We could make the ring-buffer index in sha1_to_hex() and
get_pathname() unsigned to be on the safe side to resolve this, but
let's make it explicit that we are wrapping around at whatever the
number of elements the ring-buffer has.  The compiler is smart enough
to turn modulus into bitmask for these codepaths that use
ring-buffers of a size that is a power of 2.
