Subject: builtin/replace: make hash size independent
X-Git-Tag: v2.24.0-rc0~40^2~25
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=28ba1830d0533007d5cbc1110880c6599296029a;p=thirdparty%2Fgit.git

builtin/replace: make hash size independent

Instead of using GIT_SHA1_HEXSZ and hard-coded constants, switch to
using the_hash_algo.
