test-init.sh failure on AIX 7.1

[Bruno Haible]

Hi Jim,

The recently added test-init.sh test fails on AIX 7.1:

--- exp 2012-01-28 18:51:15.000000000 +0000
+++ out 2012-01-28 18:51:15.000000000 +0000

  +++ in
- +xyz
+ + xyz
FAIL: test-init.sh

The reason is that these commands

$ touch empty
$ echo xyz > in
$ diff -u empty in
--- empty       2012-01-28 19:00:16.000000000 +0000
+++ in  2012-01-28 19:00:20.000000000 +0000

produce a unified diff where a space is inserted in column 1 (like in context
diffs).

$ type diff
diff is hashed (/bin/diff)

Find attached a possible fix. (Careful: It contains literal tabs.)

OK to apply?
