[PULL 02/10] test-keyval: Demonstrate misparse of ', ' with implied key

[Kevin Wolf]

From: Markus Armbruster <armbru@redhat.com>

Add a test for "val,,ue" with implied key.  Documentation says this
should parse as implied key with value "val", then fail.  The code
parses it as implied key with value "val,ue", then succeeds.  The next
commit will fix it.
