patch 9.1.0056: wrong number of trailing spaces inserted after blockwise put Commit: https://github.com/vim/vim/commit/6638ec8afa9875ff565020536954c424d5f6f27d Author: VanaIgr <vanaigranov@gmail.com> Date: Thu Jan 25 21:50:41 2024 +0100 patch 9.1.0056: wrong number of trailing spaces inserted after blockwise put Problem: Incorrect number of trailing spaces inserted for multibyte characters when pasting a blockwise register in blockwise visual mode (VanaIgr) Solution: Skip over trailing UTF-8 bytes when computing the number of trailing spaces (VanaIgr) When pasting in blockwise visual mode, and the register type is <CTRL-V>, Vim aligns the text after the replaced area by inserting spaces after pasted lines that are shorter than the longest line. When a shorter line contains multibyte characters, each trailing UTF-8 byte's width is counted in addition to the width of the character itself. Each trailing byte counts as being 4 cells wide (since it would be displayed as <xx>). closes: #13909 Signed-off-by: VanaIgr <vanaigranov@gmail.com> Signed-off-by: Christian Brabandt <cb@256bit.org>
