respect the user's values for $LESS, if already set #66

Closed ellemenno closed 10 years ago

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.

Thanks for the patch!
