settings.json will have "prefetch-enabled": 1, because of line line 420 tr_variantDictAddInt

whereas it will be "prefetch-enabled": true, with line 420 as tr_variantDictAddBool

prefetch-enabled: Boolean (default = true). When enabled, Transmission will hint to the OS which piece data it's about to read from disk in order to satisfy requests from peers. On Linux, this is done by passing POSIX_FADV_WILLNEED to ​posix_fadvise(). On OS X, this is done by passing F_RDADVISE to ​fcntl(). This defaults to false if configured with --enable-lightweight.
