Pod problems & fixes

Files: pod/perldiag.pod
Subject: pod2text expands B<-i>C<.bak> to -i`.bak'.  With a quote in
         the middle, it looks like it should be typed in verbatim.
         `-i.bak' is better.

Files: pod/pod2html.PL
Subject: "mailto:" is case-sensitive in URLs.

Files: lib/Term/Complete.pm lib/subs.pm pod/perlop.pod pod/perlembed.pod
       pod/perlguts.pod
Subject: Missing empty lines

Files: INSTALL pod/perlguts.pod
Subject: change `the section on L<..>' to `L<..>', because pod2*
         inserts the "the section on".

Files: pod/perlmod.pod pod/perlcall.pod
Subject: "perl5.00X" -> "perl5.00X or higher"

Files: pod/perldata.pod pod/perldiag.pod pod/perlpod.pod
