|
Fix wide glyphs breaking "nowrap" mode |
|
|
|
Consider the following example: |
|
|
|
printf '\e[?7l';\ |
|
for i in $(seq $(($(tput cols) - 1))); do printf a; done;\ |
|
printf '🙈\n';\ |
|
printf '\e[?7h' |
|
|
|
Even though MODE_WRAP has been disabled, the emoji appeared on the next |
|
line. This patch keeps wide glyphs on the same line and moves them to |
|
the right-most possible position. |
