[rancid] jrancid excess revisions due to expect prompt mismatches?

[Chuck Liggett]

While querying a Juniper SRX 650 firewall cluster from a CentOS 6.4 box running Rancid 2.3.6 (rpm from Epel), Expect 5.44.1.15,
where Rancid is run out of /etc/cron.d/rancid and scheduled every quarter hour:

Several times a day, I get excess revisions where it looks as though a Juniper Rancid command appears in the body of the config as if more than one command is being sent in response to a prompt.

Every time I run it manually in expect debugging mode, it does not experience the issue.

Here's an illustration:

Sometimes, the commands are well within the body of other command output, like in this example:
