Escape minus signs in man pages

http://lintian.debian.org/tags/hyphen-used-as-minus-sign.html says:

  By default, "-" chars are interpreted as hyphens (U+2010) by groff,
  not as minus signs (U+002D). Since options to programs use minus
  signs (U+002D), this means for example in UTF-8 locales that you
  cannot cut and paste options, nor search for them easily.

Thanks Julian Taylor for the patch.

+.I fftw@PREC_SUFFIX@\-wisdom
 can be used to create or add to such wisdom files.  In its most
 typical usage, the wisdom file can be created to pre-plan a canonical
 set of sizes (see below) via:
 
 .ce
-fftw@PREC_SUFFIX@-wisdom -v -c -o wisdom@PREC_SUFFIX@
+fftw@PREC_SUFFIX@\-wisdom \-v \-c \-o wisdom@PREC_SUFFIX@

-.B -t
+.B \-t
 option) and the output
 .I wisdom@PREC_SUFFIX@
 file can then be copied (as root) to
 .I /etc/fftw/
 or whatever.
 
 The
-.I fftw@PREC_SUFFIX@-wisdom
+.I fftw@PREC_SUFFIX@\-wisdom
 program normally writes the wisdom directly to standard output, but this
 can be changed via the
-.B -o

 If the system wisdom file

 already exists, then
-.I fftw@PREC_SUFFIX@-wisdom
+.I fftw@PREC_SUFFIX@\-wisdom
 reads this existing wisdom (unless the
-.B -n
+.B \-n
 option is specified) and outputs both the old wisdom and any
 newly created wisdom.  In this way, it can be used to add new transform
 sizes to the existing system wisdom (or other wisdom file, with the 
-.B -w
+.B \-w
 option).
 .SH SPECIFYING SIZES
 Although a canonical set of sizes to optimize is specified by the 
-.B -c
+.B \-c
 option, the user can also specify zero or more non-canonical transform
 sizes and types to optimize, via the 
 .I SIZE
 arguments following the option flags.  Alternatively, the sizes to
 optimize can be read from standard input (whitespace-separated), if a
 .I SIZE
