Display existing hard links in result sets
This is a breaking change in the plain text output,
but somehow the list displayed in case of existing hard links
was arbitrary, since the all the hardlinked filenames were not displayed.
Here's a sample JSON result with this patch:
{
"file_size": 9216,
"paths": [
"test_tree/f09-1_5.raw",
"test_tree/f09-4_5.raw"
],
"links": {
"test_tree/f09-1_5.raw": [
"test_tree/f09-2_5.raw",
"test_tree/f09-3_5.raw"
],
"test_tree/f09-4_5.raw": [
"test_tree/f09-5_5.raw"
]
}
}
Here the 5 files have the same contents, but there are two hardlink groups:
"test_tree/f09-1_5.raw"
"test_tree/f09-2_5.raw"
"test_tree/f09-3_5.raw"
are hard-linked, and
"test_tree/f09-4_5.raw"
"test_tree/f09-5_5.raw"
are hard-linked.
Here's the same set displayed With the regular text output:
Group #5 (2 files * 9216 bytes):
test_tree/f09-1_5.raw
test_tree/f09-2_5.raw
test_tree/f09-3_5.raw
test_tree/f09-4_5.raw
test_tree/f09-5_5.raw
(The link file names are indented using 1 space character.)

/usr/bin/vam
/usr/bin/vim-addons
Group #2 (2 files * 292 bytes):
/usr/bin/pip
/usr/bin/pip2
Group #3 (3 files * 1134 bytes):
/usr/bin/gajim
/usr/bin/gajim-history-manager
/usr/bin/gajim-remote
Group #4 (2 files * 1303 bytes):
/usr/bin/pdftexi2dvi
/usr/bin/texi2pdf
Group #5 (7 files * 4791 bytes):
/usr/bin/ansible
/usr/bin/ansible-console
/usr/bin/ansible-doc
/usr/bin/ansible-galaxy
/usr/bin/ansible-playbook
/usr/bin/ansible-pull
/usr/bin/ansible-vault
(...)
```
```
% goduf -summary /usr/share/doc
2018/04/07 21:48:23 Final count: 5970 duplicate files in 1920 sets
2018/04/07 21:48:23 Redundant data size: 107594575 bytes (102 MiB)
```
Use `goduf -h` to get the list of available options.
*Note for Windows users:* goduf does not normalize paths on Windows, so be careful not to specify the same path twice.
On Linux, hard links are automatically excluded.
