Bug#567041: vim-common: xxd -r -p data loss

[Nikolai Kondrashov]

Package: vim-common
Version: 2:7.2.284-1
Severity: grave
Justification: causes non-serious data loss

The attached input file (logitech_precision_gamepad_hidrd.txt) is
interpreted by xxd -r -p incorrectly. In effect, not according to manual,
which states:

    Use the combination -r -p to read plain hexadecimal dumps without line
    number information and without a particular column layout. Additional
    Whitespace and line-breaks are allowed anywhere.

The following command:
cat logitech_precision_gamepad_hidrd.txt | xxd -r -p | hexdump -C

results in the following output:
00000000  05 01 09 04 a1 01 a1 02  75 08 95 02 15 00 26 ff  |........u.....&.|
00000010  25 01 45 01 05 09 19 01  29 0a 81 02 06 00 ff 75  |%.E.....)......u|
00000020

which is incorrect.

While the following command:
cat logitech_precision_gamepad_hidrd.txt | tr -d ' \n' | xxd -r -p | hexdump -C

results in the correct output:
00000000  05 01 09 04 a1 01 a1 02  75 08 95 02 15 00 26 ff  |........u.....&.|
