Hi,

I recently started checking for differences between nroff and mandoc
output for the NetBSD manpages. And noticed a small spacing difference
between the tools. When a sentence ends with a macro followed by a
punctuation mark mandoc does only output a single space character but
nroff adds two.

By example with the select(2) man page :

njoly@lanfeust [~]> cat /usr/share/man/man2/select.2
[...]
a larger definition of
.Dv FD_SETSIZE
before the inclusion of
.In sys/types.h .
The kernel will cope,and the userland libraries provided with the
system are also ready for large numbers of file descriptors.
[...]

njoly@lanfeust [~]> nroff -mandoc /usr/share/man/man2/select.2
[...]
     providing a larger definition of FD_SETSIZE before the inclusion of
     <sys/types.h>.  The kernel will cope,and the userland libraries provided
     with the system are also ready for large numbers of file descriptors.

njoly@lanfeust [~]> mandoc /usr/share/man/man2/select.2

     by providing a larger definition of FD_SETSIZE before the inclusion of
     <sys/types.h>. The kernel will cope,and the userland libraries provided
     with the system are also ready for large numbers of file descriptors.

Thanks in advance,
Regards.
