Should we only show guesses that matter?

Right now guess_coord_axis(verbose=True) prints all matches, even for variables that already have the appropriate attributes.
Should we only show the guesses that matter (i.e., the guess for variables with missing attributes)?

I think it gets even more confusing when multiple guesses are shown, such as this:

I think 'isobaricInhPa' is of type 'Z'. It matched re.compile('(z|nav_lev|gdep|lv_|[o]*lev|bottom_top|sigma|h(ei)?ght|altitude|depth|isobaric|pres|isotherm)[a-z_]*[0-9]*')
I think 'isobaricInhPa' is of type 'X'. It matched re.compile('x|i|nlon|ni')

The variable is correctly assigned to the Z axis, but I find the print a bit confusing.
