Add the ability to prefix something to the pathname to "checkout-cache.c"
This basically makes it trivial to use checkout-cache as a "export as
tree" function. Just read the desired tree into the index, and do a
checkout-cache --prefix=export-dir/ -a
and checkout-cache will "export" the cache into the specified directory.
NOTE! The final "/" is important. The exported name is literally just
prefixed with the specified string, so you can also do something like
checkout-cache --prefix=.merged- Makefile
to check out the currently cached copy of "Makefile" into the file
".merged-Makefile".

[PATCH] Usage-string fixes.
Usage string fixes to make maintenance easier (only one instance

Also diff-cache and read-tree usage text have been corrected to
match their up-to-date features. Earlier, neither "--cached"
form of diff-cache nor "-m single-merge" form of read-tree were

[PATCH] Teach read-tree about commit objects
Updates read-tree to use read_tree_with_tree_or_commit_sha1()

this patch.
The change involves a slight modification of how it recurses down
the tree. Earlier the caller only supplied SHA1 and the recurser
read the object using it, but now it is the caller's responsibility
to read the object and give it to the recurser. This matches the
way recursive behaviour is done in other tree- related commands.

[PATCH] Do not run useless show-diff on unmerged paths repeatedly.
When run on unmerged dircache, show-diff compares the working
file with each non-empty stage for that path. Two out of three

Upper layer SCMs like Cogito are expected to find out mode/SHA1
