I suspect that this has been adequately answered already, but just to
flog the dead horse a little harder:

"tla delta foo--release--0.7.0 foo--release--0.7.1 mypatch" will create
a directory "mypatch" which represents the differences in question,
including new/removed/moved files, permissions changes, etc. This can be
viewed with "tla show-changeset" and applied with "tla dopatch".

If you want an original diff-style diff rather than an arch-style
patchdir, then you'll probably end up using exactly what you have, but
modified just a little:

diff -urN -x '*/{arch}/*' "$(tla library-find foo--release--0.7.0--base-0)" \
                          "$(tla library-find foo--release--0.7.1--base-0)"

Though if you want everything represented nicely, an arch-style diff
(from 'tla delta') is The Right Thing.
