If you are scripting, we usually encourage the use of "plumbing"
commands whose output is guaranteed not to change ("show" is a
"porcelain" command intended to be used by end-users, and it's possible
that its behavior might change from version to version).
The plumbing command to get a directory listing for a tree is "git
ls-tree" (try the "--name-only" option for terse output, and use "-z" if
you want to be robust in the face of filenames with funny characters).

Doesn't this put "tree HEAD:foo", as printed by "git show", at the top
of your filelist? Another reason to use ls-tree.

The plumbing for this is "git cat-file blob ...".
