--g-fatal-warnings option should remove "REAL" from the last arguments

[osayama]

In 20151223 version of paps, I got the following issue.

paps -h and paps's man pages describe '--g-fatal-warnings' differently

paps.1 man page haven't described about '--g-fatal-warnings' yet but
we are applying the following patch for paps.1 so this issue was raised.

I checked that paps.c and it looks to me that updated man page is
right because do_fatal_warnings is defined as gboolean. So I think
paps.c should remove "REAL" from the last arguments.

% ./paps --help |& grep g-fatal-warnings
--g-fatal-warnings=REAL Set glib fatal warnings
% grep do_fatal_warnings paps.c
gboolean do_fatal_warnings = FALSE;
{"g-fatal-warnings", 0, 0, G_OPTION_ARG_NONE, &do_fatal_warnings,
if (do_fatal_warnings)
