[libvirt] [PATCH 17/24] command.html.in: Kill useless spaces in <pre/>
Michal Privoznik
mprivozn at redhat.com
Mon Nov 14 09:34:03 UTC 2016
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.
