input: dawdle after an ESC also when --rawsequences is used

Browse Source 
When keypad() is set to FALSE, like for verbatim input, ncurses is
not waiting its fifty milliseconds after an ESC to see if another
code will follow it, so nano itself will have to pause a little.

Otherwise 'solitary' could get set to TRUE when in fact the ESC
is followed very closely by another code.

This fixes https://savannah.gnu.org/bugs/?58955.

Bug existed since version 2.6.2, commit f2150d3f.
