Open Stack

Sorry, typed it quickly.

There was a discussion on this on the ML previously. 

It's semi-colons between the values and commas between the keys

foo=a;b;c, bar=d;e;f

and the more-common case of single value would be

foo=a, bar=b

... this keeps it compatible with DEFINE_list() of gflags.

I don't like the use of commas and semicolons, and you just made the error
here that I was worried about. A semicolon has a higher "precedence" than
a comma, if you will, and is used to separate clauses. You used a
semicolon between linux;windows in the above example, then commas between
the other clauses, but forgot on the magic_sauce and cpu_min_max clauses.

IMHO we should use commas to separate the various values, and semicolons
in between the keys.

Thoughts?
