Clarify g_spawn_*() behaviour without full path

Browse Source 
Document the previously uncovered case of calling g_spawn_async_with_pipes()
without a full path but no G_SPAWN_SEARCH_PATH. This runs programs from the
current directory, which might be unexpected and even dangerous in some corner
cases.
