Three bugs in pod2html

Three bugs in pod2html

I had three problems with the pod2html distributed with perl 5.00399:

1. The HTML code generated begins with a series of hyperlinks to all
   sections of the file.  Pod directives occurring in the section
   titles (=head directives) were not translated.

2. C<foo()> sets translates to <CODE>foo</CODE> -- the () disappear.

3. Perlpod promises that example code gets typeset with tab stops
   every 8 columns.  HTML makes no such promise, hence pod2html must
   expand tabs.

The first three hunks of the patch below solve #1, hunk 4 fixes a
call to &process_text with the wrong number of args, hunk 5 solves #3
and hunk 6 solves #2.x
