add -p: avoid use of undefined $key when ReadKey -> EOF
b5cc003253 (add -i: ignore terminal escape sequences, 2011-05-17) add an additional check to the original code to better handle keys for escape sequences, but failed to account for the possibility the first ReadKey call returned undef (ex: stdin closes) and that was being handled fine by the original code in ca6ac7f135 (add -p: prompt for single characters, 2009-02-05) Add a test for undefined and encapsulate the loop and the original print that relied on it within it. After this, the following command (in a suitable repository state) wouldn't print any error: $ git -c interactive.singleKey add -p </dev/null Signed-off-by: Carlo Marcelo Arenas Belón <carenas@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
