System Information
Operating system: Linux-5.0.0-36-generic-x86_64-with-debian-buster-sid 64 Bits
Graphics card: GeForce GTX 670/PCIe/SSE2 NVIDIA Corporation 4.5.0 NVIDIA 390.129

Blender Version
Broken: version: 2.82 (sub 1), branch: master, commit date: 2019-11-17 21:26, hash: 6d9d24e3d4
Worked: (optional)

Short description of error
There are several ways to execute the*'Make Single User'operator: from the 'Operator Search' menu, from the menu Object > Relations > Make Single User > Object & Data, via Python...
But somehow it doesn't seem to work in anew session* via 'Operator Search' > 'Make Single User' UNLESS you execute it first through any of the other methods (new sesion: when you close and open Blender).

Exact steps for others to reproduce the error

Open Blender > New fresh default file.
Duplicate default cube once or more times with ALT + D (so all the cubes share the same object data). Now we have 2 or more cubes linked.

With all cubes selected > 'Operator Search' > 'Make Single User' > 'Selected Objects'

Expected behaviour:
All the cubes now have uniqueobject data (one cube has a 'Cube'mesh data, another hasCube.001, Cube.002 and so on).

Current Behaviour:
All the cubes still remain linked and share the same object data (they share the same 'Cube' mesh data and not unique 'Cube.001', 'Cube.002'... each one).

BUT:
Don't know if this helps but the 'Operator Search' > 'Make Single User' operator works as expected by following these steps:

Open Blender > New fresh default file.
Duplicate default cube once or more times with ALT + D.
With all cubes selected > 'Object' > 'Relations' > 'Make Single User' > 'Object Data' > 'Selected Objects'
The operator works as expected: all the cubes have now unique object data (Cube, Cube.001, Cube.002...).

After this the 'Operator Search' > 'Make Single User' method works fine always as expected (in this current session).

So it works from now on with any objects or even using UNDO and try it again with the same cubes. If you close Blender, open another file, revert, etc... this unexpected behaviour remains and the 'Operator Search' > 'Make Single User' method doesn't work as described.

This is a really good report (really, clear, good steps, ..), thanks for your time and dedication.

That said, technically this is not a bug. The Make Single User operator has plenty of options:

When calling from the search bar it doesn't have any option enabled. When calling from the menu we set a few options (Object? Material? Object Data?), and these settings are saved for the next time you call this operator.
This is the same behaviour we have in 2.79 by the way.

AaAAaah! I didn't realize! (I'm so dumb!). Thanks Dalai for the explanation and for the hard work fixing and making Blender better everyday! (PD: not related but I really liked your talk in the last Blender Conference! Thanks for doing it!)

let's add some reasonable defaults. a command that doesn't do anything by default makes no sense. here is the proposed diff

OKi, since #73711 (Give Make Single User sensible defaults) was resolved, this can be closed, too
