patch 8.2.3121: 'listchars' "exceeds" character appears in foldcolumn

Commit: https://github.com/vim/vim/commit/41fb723ee97baa2f095cde601a5a144b168b7a6b

    patch 8.2.3121: 'listchars' "exceeds" character appears in foldcolumn

    Problem:    'listchars' "exceeds" character appears in foldcolumn. Window
                separator is missing. (Leonid V.  Fedorenchik)
    Solution:   Only draw the "exceeds" character in the text area.  Break the
                loop when not drawing the text. (closes #8524)
