1. Move the comment about version numbers from pcre.h.in to configure.ac 
because that's where they are now set.
2. Update all the man pages to remove the use of .br and .in because this
causes trouble for some HTML converters. Also standardised the final sections 
giving author information and revision date.
3. Update the maintain/132html man page converter to handle .nf/.fi and to barf 
at .br/.in.

29     This function studies a compiled pattern, to see if additional information can
30     be extracted that might speed up matching. Its arguments are:
31     <pre>
32     <i>code</i> A compiled regular expression
33     <i>options</i> Options for <b>pcre_study()</b>
34     <i>errptr</i> Where to put an error message
35 nigel 75 </pre>
36     If the function succeeds, it returns a value that can be passed to
37     <b>pcre_exec()</b> via its <i>extra</i> argument.
38 nigel 63 </P>
39     <P>
40     If the function returns NULL, either it could not find any additional
41     information, or there was an error. You can tell the difference by looking at
42     the error value. It is NULL in first case.
43     </P>
44     <P>
45     There are currently no options defined; the value of the second argument should
46     always be zero.
