pretty: recalculate duplicate short hashesrs/pretty-add-again
b9c6232138 (--format=pretty: avoid calculating expensive expansions
twice) optimized adding short hashes multiple times by using the
fact that the output strbuf was only ever simply appended to and
copying the added string from the previous run. That prerequisite
is no longer given; we now have modfiers like %< and %+ that can
cause the cache to lose track of the correct offsets. Remove it.
