Paul J. Lucas has proposed merging lp:~paul-lucas/zorba/pjl-misc into lp:zorba.

Commit message:
Fixed handling of what is most likely a mistake on the part of the user in a 
picture string, e.g., "1,000,00" where there are multiple grouping intervals, 
but they're not equally spaced.

Requested reviews:
  Paul J. Lucas (paul-lucas)
