[flashrom] flashrom(8): HTML preview using ManPageRenderer failed

[Ivan Shmakov]

The flashrom(8) revision currently in trunk fails HTML
    conversion:

--cut: http://www.flashrom.org/trac/flashrom/browser/trunk/flashrom.8 --
    Warning: HTML preview using ManPageRenderer failed (Exception:
    Running (/usr/bin/groff -Thtml -P -r -P -l -mandoc ) failed: 0,
    <standard input>:566: warning [p 1, 86.8i]: cannot adjust line .)
--cut: http://www.flashrom.org/trac/flashrom/browser/trunk/flashrom.8 --

It seems that the regression is due to r1437 [1], as r1412 [2]
    renders without an error.
