[PATCH] Documentation: improve the example of overriding LESS via core.pager

[Patrick Palka <patrick@parcs.ath.cx>]

You can override an option set in the LESS variable by simply prefixing
the command line option with `-+`. This is more robust than the previous
example if the default LESS options are to ever change.
