other-holidays can have dates far away and mark holidays fails

[Miguel V. S. Frasson]

Dear emacs-pretest-bug list

User defined holidays stored in `other-holidays' may contain dates
from months that are not displayed now.  These dates are not checked
when `mark-calendar-holidays', causing error.

To reproduce the bug, follow the instructions

1) call emacs with the following command line

emacs -Q --eval \
"(progn \
 (setq debug-on-error t) \
 (setq other-holidays '('((( 2 27 2006) \"Emacs bug\")))))"

2) Type the following

M-x calendar RET  ; call calendar
x                 ; mark-calendar-holidays

3) We get the following backtrace

Debugger entered--Lisp error: (wrong-type-argument wholenump -41)
 move-to-column(-41)
 calendar-cursor-to-visible-date((2 27 2006))
 mark-visible-calendar-date((2 27 2006) holiday)
 mark-calendar-holidays()
 call-interactively(mark-calendar-holidays)

Note: we are in May 2006, and calendar displays April to June now.

Cordially

Miguel Frasson
