[Groff] typos in utp

[Werner LEMBERG]

A typo in ch04.t, line 1338 (from archive utp_beta2.1a):

  specìal -> special

This is due to OCR I think...

Another problem is the following code in appc.t:

.IP \f(CWcase
'nf
\f(CWcase\fI value \f(CWin
  \fIpattern1\f(CW)\fP commands\fP;;         <---
 \&.
 \&.
 \&.   
  \fIpatternn\f(CW)\fP commands\fP;;         <---
\f(CWesac\fR
.fi

groff 1.17.2 prints the marked lines incorrectly; there is only one
leading space (in font CW) instead of two.  My groff version -- CVS +
not-yet-committed changes -- yields the correct result but which is
typographically wrong due to the two leading spaces (I hope that
1.18.1 gives the correct result also :-).

A similar, inverse problem exists in line 1444 of ch04.t where groff
1.17.2 prints an incorrect result while current groff formats
correctly.
