// Quoting is very awkward. In the Java classes, quoting is done
// between ' chars, with '' meaning a single ' char. The problem is that
// in Excel, it is legal to have two adjacent escaped strings. For
// example, consider the Excel format "\a\b#". The naive (and easy)
// translation into Java DecimalFormat is "'a''b'#". For the number 17,
// in Excel you would Get "ab17", but in Java it would be "a'b17" -- the
// '' is in the middle of the quoted string in Java. So the trick we
// use is this: When we encounter a ' char in the Excel format, we
// output a \u0000 char into the string. Now we know that any '' in the
// output is the result of two adjacent escaped strings. So After the
// main loop, we have to do two passes: One to eliminate any ''
// sequences, to make "'a''b'" become "'ab'", and another to replace any
// \u0000 with '' to mean a quote char. Oy.
