i3-sensible-pager: sanitize LESS environment variable (#5111)
When an error is encountered such as "The configured command for this shortcut
could not be run successfully", the "show errors" button on i3-nagbar doesn't
work if $PAGER is less, and $LESS contains either the -E or -F flag (the
window pops up, but immediately disappears).
Strip these flags from the LESS environment variable before invoking $pager.
