 New summary:

 py-attrs --> py-hypothesis --> py-attrs\\
 Via **test dependency** py-attrs --> py-hypothesis\\
 Causes infinite loop in `port rdeps --full py-attrs`

 Old summary:

 Here is a fun little puzzle for a cold Friday night.  I can't tell if this
 is a base bug or a port bug.  Current base 2.6.4, fresh build, fresh
 selfupdate, no ports installed.  This makes an infinite loop with console
 spewage:
 {{{
 port rdeps --full py38-attrs
 }}}
 py38-attrs @20.3.0_0 \\
 py38-hypothesis @5.48.0_0 \\
 macOS 10.14.5 18F132 \\
 Xcode 10.2.1 10E1001

 There is a circular dependency py38-attrs --> py38-hypothesis -->
 py38-attrs.  However, I am confused because py38-hypothesis is only a
 **test** dependency of py38-attrs, not a **build** or **library**
 dependency.  This does not loop unless `--full` is included.

 So which one is this?
 * Test dependency does not matter.  It is still a circular dependency, and
 one of the ports has a bug.
 * Test dependency is allowed to be circular.  It is a bug in `port rdeps`.
 * Don't care because nobody should ever run `port rdeps --full`.
 Your thoughts?
