Update README to display better in markdown

Use <stdarg.h> to pass arguments correctly, as ack/util/util.c
already uses <stdarg.h> the same way.

-The file 'table' in this directory contains a back end table for the

-for words and 4 bytes for pointers. The table must be preprocessed first
-by the C preprocessor.
-The file "whichone.h" specifies which code generator is generated:
-it #defines either TBL68000 or TBL86020, and it defines WORD_SIZE to either
-2 or 4.
-The m68k4(TBL68000) cg can very well be used for the MC68010 processor,
-for it makes rather efficient use of the 68010 loop mode.

-The file 'table' in this directory contains a back end table for the
-MC68020 processor as well as one for the MC68000. Both tables use 2 or 4 bytes
-for words and 4 bytes for pointers. The table must be preprocessed first
-by the C preprocessor.
-The file "whichone.h" specifies which code generator is generated:
-it #defines either TBL68000 or TBL86020, and it defines WORD_SIZE to either
-2 or 4.
-The m68k4(TBL68000) cg can very well be used for the MC68010 processor,
-for it makes rather efficient use of the 68010 loop mode.
-
-The mach.[ch] files are also suitable for both the m68020 and the m68k[24].

-The file 'table' in this directory contains a back end table for the
-MC68020 processor as well as one for the MC68000. Both tables use 2 or 4 bytes
-for words and 4 bytes for pointers. The table must be preprocessed first
-by the C preprocessor.
-The file "whichone.h" specifies which code generator is generated:
-it #defines either TBL68000 or TBL86020, and it defines WORD_SIZE to either
-2 or 4.
-The m68k4(TBL68000) cg can very well be used for the MC68010 processor,
-for it makes rather efficient use of the 68010 loop mode.
-
-The mach.[ch] files are also suitable for both the m68020 and the m68k[24].

 \fIAck\fP accepts the following flags:
 .IP \-m\fImachine\fP
 This flag tells \fIack\fP to generate a load file for \fImachine\fP.
-\fIMachine\fP can also be used as the program call
-name, instead of \fIack\fP.
-e.g. \fIack \-mi86 file.p\fP is equivalent to \fIi86
-file.p\fP.
 .IP \-o
 Use the next argument as the name of the resulting file.
 \fIAck\fP produces \fIa.out\fP or \fIe.out\fP by default.
