Subject: [PATCH] Fix saving of po2 values

It was very broken, although it just happened to work for the values
dirk had in his own XML file (0 and 0.800 bar).  Because of confusion
with number of digits it would save 1.080 bar as 1.80 bar.

Use our "show_milli()" helper for showing things that are in milli-units
(which is what we tend to use for most of our values: mK, mbar, mm, ml)
