I've seen that man pages, as generated by the version of pandoc we
use, show single dashes in option names instead of double ones (-
versus --). After bringing it up with upstream
(http://groups.google.com/group/pandoc-discuss/browse_thread/thread/9c4589a4001d42f9/95ee8dae8932dc93

),
it seems that this is a known behaviour of pandoc that has been
improved in newer versions.

Until then, let's use correctly double dashes; from the two options in
the above thread, I chose to use \-- as that doesn't change the actual
output; whereas ``--nodes`` make this a code block, which will look
differently from a short option and could change how the output looks
(e.g. when in a bold span).

Additionally, I've removed two cases where unescape em was explicitly
intended, as that makes automated checking harder and we can use other
formatting.

This changes from the current hardcoded defaults to the cluster
policy. The command line options now override the defaults from the
cluster, and the tiered spec mode is always enabled.

Also fixes a tiny typo in the man page (together with the man page
updates).

For the standard specs, hspace currently takes separate options for
the memory, disk and VCPUs. For the tiered specs, which were
introduced later, it takes a single option with all three values
combined.

This patch adds a backward-incompatible change to the standard spec,
basically moving it to the same single option format, which is a bit
more simple (both in the code and on the command line). This is
"needed" for future changes, where the command line will just
overwrite what we get from cluster, instead of setting the starting
point.

Currently, hspace can only output a machine-readable format that
(while detailed) is hard to parse quickly by people. This patch adds
(and enables by default) a human-readable output that shows the most
important metrics in a simple format.

Most of the work of the patch is in moving the display of various
metrics from the 'main' function to separate functions, each of which
can output either a machine or human intended format.

The patch also corrects a bug in the CPU efficiency display: before,
the efficiency was computed as instance virtual CPUs divided by total
physical CPUs, which is almost always supra-unitary. More correct is
to divide by the total virtual CPUs, which shows a more meaningful
number (when the p-to-v CPU ratio has been defined correctly).
