Erroneous "Missing subversion property on Portfile" error

[ryandesign (Ryan Carsten Schmidt)]

$ port lint zlib
--->  Verifying Portfile for zlib
Error: Missing subversion property on Portfile, please execute: svn ps svn:keywords Id Portfile
Error: Missing subversion property on Portfile, please execute: svn ps svn:eol-style native Portfile
--->  2 errors and 0 warnings found.

This is false:

$ svn pl -v $(port file zlib)
Properties on '/Users/rschmidt/macports/dports/archivers/zlib/Portfile':
  svn:keywords
    Id
  svn:eol-style
    native

The debug output reveals the problem:

DEBUG: Property svn:keywords is "svn: warning: Can't open file '/Users/rschmidt/.macports/opt/local/var/macports/build/_Users_rschmidt_macports_dports_archivers_zlib/zlib/work/.home/.subversion/servers': Permission denied
Id", should be "Id"
Error: Missing subversion property on Portfile, please execute: svn ps svn:keywords Id Portfile

Also:

$ sudo port lint zlib
--->  Verifying Portfile for zlib
--->  0 errors and 0 warnings found.

So we should just ignore the error output from the svn command.

The attached patch would do this. The problem is this would eliminate possibly helpful error output in the case that svn returns with a nonzero exit code. I don't know if there's a way to get [exec] to put the stdout and stderr in separate variables; that would be helpful.

No longer relevant after we switched to Git.
