Remove Trailing Spaces Only from Specified Lines

Only the specified lines (e.g., line 2) have their trailing spaces removed.

Line three

After (removing trailing spaces from line 2):

Line one     
Line two
Line three

Line two      
Line three

Line two      
Line three

Replace Trailing Spaces with a Placeholder

Every trailing whitespace sequence is replaced with a custom placeholder (e.g., [TS]).

Before:

Hello world      
Test line

After (with placeholder "[TS]"):
