Subject: contrib/git-resurrect.sh: use hash-agnostic OID pattern
X-Git-Tag: v2.30.0-rc0~144^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=e37eae0c1e13cb418947383f7c803d9463bfa3d7;p=thirdparty%2Fgit.git

contrib/git-resurrect.sh: use hash-agnostic OID pattern

Since Git now supports hashes other than SHA-1, the hash length isn't
guaranteed to be 40 characters. Replace $_x40 with a hash-agnostic OID
pattern.
