lintpkgsrc, distfile cleaning, and a surprising result

[Greg Troxel <gdt%lexort.com@localhost>]

I ran `lintpkgsrc -mr` and `lintpkgsrc -or` recently.  I've been tending
not to, as I often share a directory between the stable branch and
pkgsrc-current.

After, looking at my distfile dir, there were many versions of a bunch
of rust crates.  That seemed obviously buggy.  But looking more closely
at one picked semi-randomly:

  $ find . -name distinfo|xargs egrep zerocopy-derive|egrep SHA512 | awk '{print $2}' | sort |uniq -c
     1 (meli-0.8.12/zerocopy-derive-0.7.35.crate)
     1 (zerocopy-derive-0.7.11.crate)
     1 (zerocopy-derive-0.7.31.crate)
     7 (zerocopy-derive-0.7.32.crate)
     1 (zerocopy-derive-0.7.33.crate)
    66 (zerocopy-derive-0.7.35.crate)
     1 (zerocopy-derive-0.8.18.crate)
     1 (zerocopy-derive-0.8.21.crate)
     4 (zerocopy-derive-0.8.23.crate)
     4 (zerocopy-derive-0.8.24.crate)
    16 (zerocopy-derive-0.8.25.crate)
    33 (zerocopy-derive-0.8.26.crate)
     8 (zerocopy-derive-0.8.27.crate)

the bug is not in lintpkgsrc :-)

I doubt there's anything to be done, but I thought I'd mention it in
case anyone else is cleaning up distfiles and finding it odd.
