In the past, Debian's `cal` used to color the current day which was
enough for my use. But recently this changed to the more traditional
`cal` output with no highlight. So use `ncal` directly and add other
useful options.
# Use short `ip` output per default.
alias ip='ip -brief -color=auto'
+# Calendar with traditional output (-b), weeks starting on Monday (-M), week
+# numbers (-w) and the previous, current and next month (-3)
+alias cal='ncal -b -M -w -3'
