Add *.tmp.meta to .gitignore and to "make clean".

Explicitly use "du -k" to set block size in t/test.sh.

Commit e3514812 (Explicitly select the "du" block size in t/test.sh)
used the parameter "-B 1024" which isn't portable. Now use "du -k"
to explicitly get output in kilobytes.

At least du(1) on Linux (GNU coreutils), Mac OS X, FreeBSD, NetBSD,
and OpenBSD support this option.

Stop checking for empty stat values from recursive_dirlist().

Remove the "if pst:" guard in index-cmd.py, since it doesn't appear to
be possible for recursive_dirlist() to return None for the stat value.
