Title: respect the user's values for $LESS, if already set

commander overrides any values the user may have already set for their `LESS` environment variable, and doesn't provide a way to configure what the override values will be.

this pull request changes the behavior from overriding to defaulting, so the user or host program has a chance to configure the pager behavior.
