One way to attack the problem is (1) use only one-liners for option help, and
(2) not worry about indentation so much (either in English or in German) as the
excess indenting doesn't help readability enough to justify the translation
hassle. To do that, I propose changes like the attached for comm. This will
cause 'comm --help' output to look like the following, which is good enough and
which will still work with help2man:
Usage: comm [OPTION]... FILE1 FILE2
Compare sorted files FILE1 and FILE2 line by line.
When FILE1 or FILE2 (not both) is -, read standard input.
With no options, produce three-column output. Column one contains
lines unique to FILE1, column two contains lines unique to FILE2,
and column three contains lines common to both files.
-1 suppress column 1 (lines unique to FILE1)
-2 suppress column 2 (lines unique to FILE2)
-3 suppress column 3 (lines that appear in both files)
--check-order check that the input is correctly sorted
--nocheck-order do not check that the input is correctly sorted
--output-delimiter=STR separate columns with STR
--total output a summary
-z, --zero-terminated line delimiter is NUL, not newline
--help display this help and exit
--version output version information and exit
Note, comparisons honor the rules specified by 'LC_COLLATE'.
Examples:
comm -12 file1 file2 Print only lines present in both file1 and file2.
comm -3 file1 file2 Print lines in file1 not in file2, and vice versa.
