bug#422: 23.0.60; buggy diary-float function?

[Peter Dyballa]

Hello!

The documentation does not explicitly tell it's possible to do this:

     &%%(diary-float 11 4 4) American Thanksgiving

The 11 specifies November (the eleventh month), the 4 specifies Thursday
(the fourth day of the week, where Sunday is numbered zero), and the
second 4 specifies the fourth Thursday (1 would mean "first," 2 would
mean "second," -2 would mean "second-to-last," and so on).  The month
can be a single month or a list of months.  Thus you could change the
11 above to `'(1 2 3)' and have the entry apply to the last Thursday of
January, February, and March.  If the month is `t', the entry applies
to all months of the year.

   Each of the standard sexp diary entries takes an optional parameter
specifying the name of a face or a single-character string to use when
marking the entry in the calendar.  Most generally, sexp diary entries
can perform arbitrary computations to determine when they apply.  *note
()Sexp Diary Entries::.

so I thought it would work, but I am told it does not work to prepare  
diary entries for all Thursdays of a particular month:

Bad sexp at line 3 in ~/diary: (diary-float 6 4 t) [14 times]
Bad sexp at line 4 in ~/diary: (diary-float 6 t 3) [92 times]
Bad sexp at line 5 in ~/diary: (diary-float 6 '(1 2 3 4 5) 1) [92 times]
Bad sexp at line 6 in ~/diary: (diary-float 6 '(0 1 2 3 4) 0) [92 times]

I used lines #3 and #4 because some calendar functions swap arguments  
when used in European mood.
