* fhandler.cc (fhandler_base::open): Always open NFS files with

Browse Source 
FILE_READ_EA, even when opening with O_WRONLY to allow fstat.
	* fhandler_disk_file.cc (fhandler_base::fstat_by_nfs_ea): Call
	FlushFileBuffers if file has been opened for writing.  Explain why.
	(fhandler_base::fstat_by_handle): Renew content of pc.fnoi if called
	via fstat.  Explain why.  Fix formatting.
	* path.cc (symlink_info::check): Try to open file the second time with
	FILE_READ_EA permissions since it's needed in later calls to
	fhandler_base::fstat_by_nfs_ea.
