* src/comm.c (usage): Don't align example comments in --help output,
since the extra space (sequence of two spaces) there would be
interpreted by help2man and induce an unwanted line break
in the resulting man page. Reported by Jari Aalto.

Examples:\n\
%s -12 file1 file2 Print only lines present in both file1 and file2.\n\
- %s -3 file1 file2 Print lines in file1 not in file2, and vice versa.\n\
+ %s -3 file1 file2 Print lines in file1 not in file2, and vice versa.\n\
