[PATCH] rl_redisplay: don't adjust cursor position twice for meta chars

[Grisha Levit]

The code for displaying characters with octal escapes seems to
increment the cursor position twice for each character in the escape
sequence.

printf -v s '%*s' "$((COLUMNS/5))"
PS1= LC_ALL=C bash --norc -in <<<${s// /$' \200'}
 \200 \200 \200 \200 \200 \200 \200 \200 \20
0 \200 \200 \200 \200 \200 \200
