input: wait a bit for "~" when bracketed-paste sequence is incomplete

Browse Source 
When pasting something into nano over OpenSSH_for_Windows, the final
tilde of the end-of-paste sequence can lag some 29 ms behind the rest
of the sequence, causing ncurses to split it off into a next batch of
bytes.  Accommodate for this by noticing the missing tilde and then
waiting at most one second for it to arrive.  This prevents the tilde
from appearing spuriously in the buffer after the paste.

This addresses https://savannah.gnu.org/bugs/?66858.
