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.

21 This is a convenience function for extracting a captured substring by name. The
22 arguments are:
23 .sp
24 \fIcode\fP Compiled pattern
25 \fIsubject\fP Subject that has been successfully matched
26 \fIovector\fP Offset vector that \fBpcre_exec()\fP used
27 \fIstringcount\fP Value returned by \fBpcre_exec()\fP
28 \fIstringname\fP Name of the required substring
29 \fIstringptr\fP Where to put the string pointer
30 .sp
31 The memory in which the substring is placed is obtained by calling
32 \fBpcre_malloc()\fP. The convenience function \fBpcre_free_substring()\fP can
33 be used to free it when it is no longer needed. The yield of the function is
34 the length of the extracted substring, PCRE_ERROR_NOMEMORY if sufficient memory
35 could not be obtained, or PCRE_ERROR_NOSUBSTRING if the string name is invalid.
