less: update line input so that it doesn't interfere with
screen update. Makes "man bash", [enter], [/], <enter search pattern>, [enter] more usable - manpage draws as you enter the pattern! Yay!! less: fix bug where backspace wasn't actually deleting chars less: "examine file with empty name" doesn't abort anymore. libbb: add "all fatal signals" mask. getch_nowait - 207 +207 status_print - 105 +105 examine_file 64 87 +23 move_cursor - 16 +16 m_status_print 185 195 +10 less_main 1656 1663 +7 decode_format_string 790 795 +5 test_main 403 405 +2 process0_stdin 247 249 +2 passwd_main 1070 1072 +2 less_gets 196 178 -18 buffer_print 169 71 -98 less_getch 362 138 -224 ------------------------------------------------------------------------------ (add/remove: 3/0 grow/shrink: 7/3 up/down: 379/-340) Total: 39 bytes text data bss dec hex filename 798329 740 7484 806553 c4e99 busybox_old 798368 740 7484 806592 c4ec0 busybox_unstripped
