Subject: style.css: Take the indent from the nesting

mkwb writes a reply inside what it answers now, so the indent is one
margin a level rather than nine rules counting depth, and each reply's
rail stacks with its parents' --- which is the thread view the flat
list could only approximate with a single rule.

On a narrow screen the margin goes and the rails carry it alone: at
depth 7 that is 273px of text on a 390px phone against 133px if the
desktop indent were kept, and against 350px and no nesting at all,
which is what was there before.
