Tango version 0.7.2

Today I uploaded tango 0.7.2 to CTAN.

• Corrected the counter name in the \subparagraph command (as defined for the titlesec package). This is almost cosmetic, since I doubt many people use the \subparagraph command. But it was still a real bug.
• The vertical space generated at the start of an exercise (command \exo) was far too large. Just a clumsiness on my part.

This version of the tango document class should be available on CTAN and TeXLive in one or two days.
