That was indeed on purpose. The old format was too
loosely defined and it was hard to parse the informtion
out that we wanted. Also, it was creating trouble for the
translators and we have wanted to ditch it for years.
Here's a sample of how things are done now:
static GnmFuncHelp const help_lcm[] = {
{ GNM_FUNC_HELP_NAME, F_("LCM:the least common multiple")},
{ GNM_FUNC_HELP_ARG, F_("n0:positive integer")},
{ GNM_FUNC_HELP_ARG, F_("n1:positive integer")},
{ GNM_FUNC_HELP_DESCRIPTION, F_("LCM calculates the least common
multiple of the given numbers @{n0},@{n1},..., the smallest integer
that is a multiple of each argment.")},
{ GNM_FUNC_HELP_NOTE, F_("If any of the arguments is not an integer,
it is truncated.")},
{ GNM_FUNC_HELP_EXCEL, F_("This function is Excel compatible.") },
{ GNM_FUNC_HELP_EXAMPLES, "=LCM(2,13)" },
{ GNM_FUNC_HELP_EXAMPLES, "=LCM(4,7,5)" },
{ GNM_FUNC_HELP_SEEALSO, "GCD"},
{ GNM_FUNC_HELP_END}
};
