2016-11-24lineedit: fix handling of repeating Alt-b, Alt-f, Alt-d, Alt-BackspaceRostislav Skudnov
These key combinations should repeat correctly when the keys are pressed and held. Before this change, they do this erratically - many repeats are "eaten" because they are treated as unrecognized ESC seqs: ESC 0x7f is treated by Alt+baskspace, but ESC 0x7f ESC 0x7f ESC 0x7f is unrecognized. Escape sequences corresponding to these key combinations are moved from read_line_input to lineedit_read_key. Also, these key sequences are now enabled regardless of whether FEATURE_EDITING_VI is set, since Vim does not actually support these key combinations, but they are present in readline library. function old new delta static.esccmds 93 103 +10 read_line_input 3737 3687 -50 Signed-off-by: Rostislav Skudnov <rostislav@tuxera.com> Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
