[PATCH] git-svn: propset support v2

I have incorporated Eric Wong's feedback into the git-svn propset support patch.

Issues resolved:
1) Test-case written.
2) Remove dead code.
3) Use shorter vars for formatting.
4) Fix bool comparisons.
5) Check for filesystem errors on write to .gitattribute file.
6) Use command_output_pipe() instead of open my $fh, '-|', ...
7) Refactor check for existing props.

There is a nit that I want to point out. The code does not support adding props unless there are also content changes to the files as well. You can see this in the testcase.

That is still sufficient for many people's workflows (FreeBSD at least). So I am wondering if this is OK.

I would gladly take any pointers to making it work with unchanged files either for a later diff or to wrap this up.

Thank you.
