- * For all other fonts Windows sets the margins to zero.
+ * FIXME: the message identifiers have been chosen arbitrarily,

+ * We might as well use the "real" values (anybody knows ?)
+ * The menu definition is in resources/sysres_??.rc.
+ * Once these are OK, we better use MF_BYCOMMAND here
+ * (as we do in EDIT_WM_Command()).
*
- * FIXME - When EC_USEFONTINFO is used the margins only change if the
- * edit control is equal to or larger than a certain size.
- * Interestingly if one subtracts both the left and right margins from
- * this size one always seems to get an even number. The extents of
