Subject: Only read major version when parsing less version (#606)

For versions of less that include a point version (eg 581.2), parsing
the whole version 'word' as a usize fails and causes '--no-init' to be
added to less arguments. This prevents less using the alternate screen
and mouse scrolling.

Fixes #582
