svn commit: r353532 - head/Mk/Scripts

[Bryan Drewery]

Author: bdrewery
Date: Fri May  9 22:29:30 2014
New Revision: 353532
URL: http://svnweb.freebsd.org/changeset/ports/353532
QAT: https://qat.redports.org/buildarchive/r353532/

Log:
  - Fix regression handling files with spaces from r350006.
    Separate file(1) and stat(1) output by a newline and read each line
    individually to avoid losing spaces.
  - Use <<-EOF with heredocs to avoid bad indent
  - Add some more comments
  - Quote filenames in output so it is less unclear
