3522	[patch] fix memleak at src/editor/editcmd.c:3607	and		"fix memleak at src/editor/editcmd.c:3607

spell suggest array object needs to free cur_sugg_word objects _itself_, currently we freed only the array element space of each cur_sugg_word pointer

(smarter will be an usage of g_array_set_clear_func() but this will lead us to a higher glib version dependency maybe)

(possible there are more g_strup() -> g_array_append_val() -> g_array_free(x,TRUE) -> missing g_strup freeing occurrences in MC source code)
