command.html.in: Kill useless spaces in <pre/>
The <pre/> section is rendered as-is on the page. That is, if all the lines are prefixed with 4 spaces the rendered page will also have them. Problem is if we put a box around such <pre/> because the content might not fix into it. Signed-off-by: Michal Privoznik <mprivozn@redhat.com>
