[rancid] help request after I developed new module 'vnxrancid', but it don't save output properly to configs directory

[danielc at vmware.com]

I hacked fnlogin/fnrancid pair to do some EMC VNX commands on their RHAT/Linux shell, but the only a portion of the output is not being checked into the configs directory.

I have done the following:
 NOPIPE=yes;export NOPIPE
 vnxrancid -d vnx01

I get the two files: vnx01.raw and vnx01.new

But if I do just:
 rancid-run -r vnx01 testing

The .../var/testing/configs/vnx01 file only has saved some lines like: 
!RANCID-CONTENT-TYPE: vnxrancid

The contents of the vnx01.new file looks perfect (in my opinion)

I noticed that the end of the vnx01.raw file still have lots of control characters, is this interfering with the rancid-run

whereas an UCS, N7K, Vyatta device the .raw file is much cleaner.
