Did you manage to figure out why one was better than the other? The 
differences between the functions seem rather subtle.

rl_reset_screen_size()

Does not respect the COLUMNS and ROWS environment variables.

_rl_sigwinch_resize_terminal()

Internal callback, does the same thing as
rl_reset_screen_size() except that it also respects COLUMNS and ROWS.

rl_resize_terminal()

Respects COLUMNS and ROWS and also has some logic when echo mode is 
turned on which I have not managed to understand yet.

Btw, really nice to see someone working at this. It has bugged me a long 
time.
