vim-8.0.0106 doesn't have these issues, so it may make sense to set 8.0.0386 back to ~arch. When using horizontal scroll with tab-indented file there are some issues: 1. tab-indented lines doesn't move in sync with non-indented lines 2. positioning at end of line doesn't work correctly 3. editing text near end of long line is also buggy (I have not tried to reproduce this) To reproduce: $ vi -u NONE --noplugin -c 'set nowrap' -c 'set sidescroll=1' all_test.go Jump to long line: 218G Try to use horizontal scroll, repeat several times: zl Try to jump to end of line: $ You can download all_test.go file at https://github.com/powerman/rpc-codec/blob/master/jsonrpc2/all_test.go or use any other file with long tab-indented lines.
