allow nested rust projects

Thanks, but could you explain what this change is trying to fix?

[ddavison]

sure -

Consider the following project structures:

Structure 1

$ ls
project1/
  .gitignore
  src/
  target/
  Cargo.toml
  Cargo.lock

Structure 2

$ ls
project2/
  .gitignore
  nested_project1/
    src/
    target/
    Cargo.toml
    Cargo.lock
  nested_project2/
    src/
    target/
    Cargo.toml
    Cargo.lock

In Structure #1, the current gitignore template works.
In Structure #2, the current gitignore template does not work.

With this fix, Structure #1 and Structure #2 will both work.

Thanks for that. I don't use rust, so I don't know, but I would have thought the normal thing would be to have separate repositories for each project. Are they commonly nested like this?

[ddavison]

maybe not, but it doesn't hurt :) like I said - it fits both cases

[arcresu]

It does hurt in that it would cause any directory anywhere in your project with the name target to be ignored, which could be unexpected and hard to notice on the off-chance it happens. I'd prefer to assume one project per repo and keep the rules specific, unless there's a common pattern of usage that makes this unreasonable. Thanks anyway!
