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.

14 nigel 63 .SH DESCRIPTION
15     .rs
16     .sp
17     This function studies a compiled pattern, to see if additional information can
18     be extracted that might speed up matching. Its arguments are:
19 nigel 75 .sp
20     \fIcode\fP A compiled regular expression
21     \fIoptions\fP Options for \fBpcre_study()\fP
22     \fIerrptr\fP Where to put an error message
23     .sp
24     If the function succeeds, it returns a value that can be passed to
25     \fBpcre_exec()\fP via its \fIextra\fP argument.
26     .P
27 nigel 63 If the function returns NULL, either it could not find any additional
28     information, or there was an error. You can tell the difference by looking at
29     the error value. It is NULL in first case.
30 nigel 75 .P
31 nigel 63 There are currently no options defined; the value of the second argument should
32     always be zero.
33 nigel 75 .P
34     There is a complete description of the PCRE native API in the
35 nigel 63 .\" HREF
