Trying to optimize find(1) primaries in attachment 149511 I've noticed the 3rd
argument is always expanded. This makes it harder to exclude files based on
regex or shell globs. One could try to escape meta characters with \
(backslash) but it doesn't work because \ isn't stripped in the output.

  post-install:
          (cd ${WRKSRC}/manual && ${COPYTREE_SHARE} \
                  . ${STAGEDIR}${DOCSDIR} "! -name Makefile\*")

Here's the illustration:

  $ sh -c 'cd /var/empty; echo $0' -- "*"
  *

  $ sh -c 'cd /bin; echo $0' -- "*"
  [ cat chflags ...

  $ sh -c 'cd /bin; echo $0' -- "\*"
  \*

  $ sh -c 'cd /bin; echo $0' -- "\\*"
  \*

  $ sh -c 'cd /bin; echo $0' -- "'*'"
  '*'

One way to strip quoting is via `eval' builtin:

  $ sh -c 'cd /bin; eval echo $0' -- "\*"
  *

  $ sh -c 'cd /bin; eval echo $0' -- "'*'"
  *
