Improve error messages for eat_date() and eat_regexp().

After calling mutt_extract_token(), s->dptr will typically be at the end
of the string if an error occurred.  Save a pointer to the beginning of
the expression, so it can be properly displayed in the error message.

Convert eat_date() and eat_regexp() to use the same iconv strings for
the error message.
