patch 9.1.0043: ml_get: invalid lnum when :s replaces visual selection
Problem: ml_get: invalid lnum when :s replaces visual selection
(@ropery)
Solution: substitute may decrement the number of lines in a buffer,
so validate, that the bottom lines of the visual selection
stays within the max buffer line
fixes: #13890
closes: #13892
