// #6329: When Min/Max range is set, then dates before the min
// or after the max are painted in the normal date color. They
// should be painted with MCSC_TRAILINGTEXT color. (Or we should
// add a new color to cover this case.) Feature requested by Jobi George
// 9577: We want a DAYSTATE like structure for the background
// color of dates. For highlighting. Perhaps a COLORSTATE per

// SE_MONTHALT is just like SE_MONTH except that it is used
// when the day (dd) comes before the month (mmm). This is
// important for languages like Russian where "12 October"
// and "October 12" use different strings for the word
// "October". There is no way to get the alternate string
// directly, except by creating a bogus date format that also
// has the day before the month, then throwing away the day.
// For example, if the incoming date string is
// "MMMM dd yyyy"
// we break it up into
// "MMMM" SE_MONTH
// " " SE_STATIC
// "dd" SE_DAY
// " " SE_STATIC
// "yyyy" SE_YEAR
// However, if the incoming date is
// "dd MMMM yyyy"
// we break it up into
// "dd" SE_DAY
// " " SE_STATIC
// "ddMMMM" SE_MONTHALT
// " " SE_STATIC
// "yyyy" SE_YEAR
// The extra "dd" at the beginning of SE_MONTHALT is stripped out below.
// Y2K weirdness: If we are getting the date format for the year,

// it is the active subedit), and the format year is only
