Takashi Yano 0d7bbc0bc3 Cygwin: console: Add support for REP escape sequence to xterm mode.
- In Win10 upto 1809, xterm compatible mode does not have REP
  escape sequence which terminfo declares. This patch adds support
  for "CSI Ps b" (REP). With this patch, bvi (binary editor) works
  normally in Win10 1809. Also, xterm compatible mode does not have
  "CSI Pm `" (HPA), "CSI Pm a" (HPR) and "CSI Ps e" (VPR). However,
  they do not appear to be declared by terminfo. Therefore, these
  have been pending.
