just --unstable --list --unsorted has weird behavior with includes

[neunenak]

The code in https://github.com/casey/just/blob/master/src/justfile.rs#L367-L370 that determines what order recipes will be listed in when not sorted alphabetically depends on the offset of a recipe from the beginning of its file.

E.g. if you have the justfiles:

justfile:

# newlines


default:
    echo "DEFAULT"

!include ./include.justfile

include.justfile:

alpha:
    echo "ALPHA"

beta:
    echo "BETA"

Then the output of just --unstable --list --unsorted on latest master is:

Available recipes:
    alpha
    default
    beta

instead of the default - alpha - beta order I'd expect.

#1739 has a solution for this (albeit not a working test), but it also computes the default recipe in a way different than what #1740 decided on, so I'm not sure how much of the code from 1739 is useful.

Maybe the compiler returns a Vec<PathBuf> with the paths of all the source files, in the order in which they were loaded, and then recipes are sorted first by the order in which they appear in that list, and then by order of offset?
