Add '-s' option and update the manual page. With this option, it prints

little more style(9) friendly output.  For example:

%file2c -n 8 -s -x 'const char data[] = {' '};' < /etc/motd
const char data[] = {
	0x46, 0x72, 0x65, 0x65, 0x42, 0x53, 0x44, 0x20,
	0x37, 0x2e, 0x30, 0x2d, 0x43, 0x55, 0x52, 0x52,

 By default the byte values are printed in decimal, but when the

 The prefix is used to define an array type and the suffix is used to end
 the C statement.
 The

 Fonts, for example, are a good example of this.
