Trying to optimize find(1) primaries in attachment 149511 [details] 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' -- "'*'"
