patch 8.2.0518: a terminal falls back to setting $TERM to "xterm"

Browse Source 
Problem:    A terminal falls back to setting $TERM to "xterm".
Solution:   Use "xterm-color" if more than 16 colors are supported and
            "xterm-256color" if at least 256 colors are supported.
            (closes #5887)
