From aca085e577688108a2480b96a2f7077424a74e4d Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Sun, 3 Dec 2006 20:42:47 +0100 Subject: [PATCH] git-mv: search more precisely for source directory in index A move of a directory should find the entries in the index by searching for the name _including_ the slash. Otherwise, the directory can be shadowed by a file when it matches the prefix and is lexicographically smaller, e.g. "ab.c" shadows "ab/". Noticed by Sergey Vlasov.
