Don't scroll selection on the other screen |
|
|
|
Fixes garbage selections when switching to/from the alternate screen. |
|
|
|
How to reproduce: |
|
|
|
- Be in primary screen. |
|
- Select something. |
|
- Run this (switches to alternate screen, positions the cursor at the |
|
bottom, triggers selscroll(), and then goes back to primary screen): |
|
|
|
tput smcup; tput cup $(tput lines) 0; echo foo; tput rmcup |
|
|
|
- Notice how the (visual) selection now covers a different line. |
|
|
|
The reason is that selscroll() calls selnormalize() and that cannot find |
|
the original range anymore. It's all empty lines now, so it snaps to |
|
"select the whole line". |
