Commented out nonexistent operations.

The original manual documented predefined operations test-system-version
and feature-dependent-op.  These operation classes do not appear in the
current version of asdf.lisp, so I have excised them from the manual.

@deffn Operation test-system-version &key minimum
Asks the system whether it satisfies a version requirement.
The default method accepts a string, which is expected to contain of a
number of integers separated by #\. characters. The method is not
recursive. The component satisfies the version dependency if it has
the same major number as required and each of its sub-versions is
greater than or equal to the sub-version number required.

If that doesn't work for your system, you can override it. I hope
you have as much fun writing the new method as @verb{|#lisp|} did
reimplementing this one.

@deffn Operation feature-dependent-op
An instance of @code{feature-dependent-op} will ignore any components
which have a @code{features} attribute, unless the feature combination
it designates is satisfied by @code{*features*}. This operation is
not intended to be instantiated directly, but other operations may
inherit from it.
