Unfortunately, cargo clippy fails when testing fuzz_seq_parse_number:
```
error[E0603]: module `number` is private
--> fuzz_targets/fuzz_seq_parse_number.rs:9:13
|
9 | use uu_seq::number::PreciseNumber;
| ^^^^^^ private module
|
note: the module `number` is defined here
--> /home/drinkcat/dev/coreutils/coreutils/src/uu/seq/src/seq.rs:24:1
|
24 | mod number;
| ^^^^^^^^^^
```
But we can still fix the rest...
Minor manual cleanup - inlined many format args. This makes the code a bit more readable, and helps spot a few inefficiencies and possible bugs. Note that `&foo` in a `format!` parameter results in a 6% extra performance cost, and does not get inlined by the compiler (yet).
