I am beginning to think this has more to do with network than filesystem:

Given that all seemed well with the 30 Mar kernel, to check I wasn't
being silly, I went back to the "broken" kernel, which is of April
3 vintage.
I did a fresh cvs checkout, and once again saw chunks of binary inside
text files.
I tried the untar 4 copies of pkgsrc simultaneously and compare the results
"test", and it was fine.

Now I booted a kernel built on morden (so not from one of my suspect
source trees) from April 7 code. I did a fresh checkout, and during
checkout, I see:
