When we quit pager, the return value 1 is returned and command_more()
interprets it as error.
when lua loader gets error from command, it will try to
interpret it once more, so we get the same file shown once more.
There is no reason why we should return error from command_more().

libsecureboot can tell us if the most recent file opened was
verfied or not.
If it's state is VE_UNVERIFIED_OK, skip if variable
matches one of the restricted prefixes.

Since we do free subtopic and desc in help_getnext(), we need to set them also
NULL, so we make sure we dont get double free().

With r328289 we attempt to make sure we free the resources allocated in
help_getnext(), however, it is possible that we get no resources allocated
and help_getnext() will return early.
Make sure we have pointers set to NULL early in help_getnext().

Right now, we'll leak memory when we display a help topic because we
don't free t, s, d that we've just used when breaking out of the loop.
NB: coverity just reported t, but s and d also leak.
