Prior to this commit, the 'print-copyright' rule in
`reproduce/analysis/make/initialize.mk` did not process
parameter 2, which can have the value 'new', that creates
a new file instead of concatenating to a pre-existing
file. This bug typically concatenated multiple copies of
`voidgals_infall.dat` together.
This commit aims to fix that bug, and appears to work
as intended.
