option: Make option help nicer to read

This adds some whitespace into the option help (including indentation)
and puts angle brackets around the type names.  Furthermore, the list
name is no longer printed as part of every line, but only once in
advance, and only if the caller did not print a caption already.

This patch also restores the description alignment we had before commit
9cbef9d68ee1d8d0, just at 24 instead of 16 characters like we used to.
This increase is because now we have the type and two spaces of
indentation before the description, and with a usual type name length of
three chracters, this sums up to eight additional characters -- which
means that we now need 24 characters to get the same amount of padding
for most options.  Also, 24 is a third of 80, which makes it kind of a
round number in terminal terms.

Finally, this patch amends the reference output of iotest 082 to match
the changes (and thus makes it pass again).
