argp test failure on NetBSD

[Bruno Haible]

Hello Sergey,

The 'argp' unit test fails on NetBSD 3.0:

stdin argp.12775 differ: char 118, line 2
stdin argp.12775 differ: char 106, line 2
stdin argp.12775 differ: char 252, line 12
FAIL: test-argp-2.sh

Since this output is not very informative, I'm changing the test to make
the comparison through "diff" instead of "cmp". Then the output looks like
this:

Note that this is with gnulib's argp implementation, not NetBSD's one.

Where does the failure come from?
