  "message": "fast-import: Allow filemodify to set the root\n\nv1.7.3-rc0~75^2 (Teach fast-import to import subtrees named by tree id,\n2010-06-30) has a shortcoming - it doesn\u0027t allow the root to be set.\nExtend this behaviour by allowing the root to be referenced as the\nempty path, \"\".\n\nFor a command (like filter-branch --subdirectory-filter) that wants\nto commit a lot of trees that already exist in the object db, writing\nundeltified objects as loose files only to repack them later can\ninvolve a significant amount of overhead.\n(23% slow-down observed on Linux 2.6.35, worse on Mac OS X 10.6)\n\nFortunately we have fast-import (which is one of the only git commands\nthat will write to a pack directly) but there is not an advertised way\nto tell fast-import to commit a given tree without unpacking it.\n\nThis patch changes that, by allowing\n\n\tM 040000 \u003ctree id\u003e \"\"\n\nas a filemodify line in a commit to reset to a particular tree without\nany need to parse it.
