            Bug ID: 240308
           Summary: security/fsh: remove redundant escapes of ordinary
                    characters
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: ports-bugs at FreeBSD.org

svn(1) diff against the ports tree

Makefile.in has a number of escapes (all following @ in the sed expression)
that serve no legitimate purpose as far as I can tell. Escaping ordinary
characters is considered undefined behavior by POSIX, and bug #229925 aims to
serve out errors for escaping of most ordinary characters to reduce friction
when some of these sequences are given special meaning.

Things seem to come out OK looking with this patch applied, but I have no way
to functionally test.
