Dry run command gives wrong result

[TimJentzsch]

When I ran cargo clean-recursive --dry-run, it claimed 1.5 TB space will be saved. But that's even more than my 1 TB SSD can hold in total.

When I then ran cargo clean-recursive, 152.3 GB was actually saved.

Maybe it's a unit conversion error?

I tested it on several cases including files of around 150GB in size, but I did not encounter this issue.
In Version 1.1.0, I added the --verbose option to display the output of cargo clean.
This might help with debugging.

I'll let you know if I encounter this again and try with the --verbose flag :)

I think it counts workspaces multiple times: one for the workspace root and then one for each sub crate.

$ cargo clean-recursive . --dry-run 
Checking "."
Checking "./crates/client"
Checking "./crates/common"
Checking "./crates/server"
Checking "./crates/websocket"
Total space that will be saved: 2.8 GB
$ cargo clean                      
     Removed 1236 files, 538.2MiB total

538.2 MiB is around 564 MB, 564*5 = 2820 MB, hence the 2.8 GB estimation.
