0fed51f76 made <prefix>_unmerged.mtz default-on so a run that turned out to need
it would not have to be repeated. It costs more than that is worth: measured on a
dense rotation dataset, it adds 2.6 s to a 7.0 s --mode scale run (+38%) and
writes 272 MB - larger than the merged .mtz, .cif and .hkl put together, and paid
by every run whether or not anything will read it.
--export-unmerged asks for it again. --no-export-unmerged stays accepted and now
does nothing, the mirror of what --export-unmerged did while the default was on.
The two fixes that came with the default-on change are kept: the file is written
in --mode mx and --mode scale and with --no-merge, and both write sites are
guarded on the output prefix, so a prefix-less run no longer writes a file called
"_unmerged.mtz".
