Valid config not found for cargo doc --open command

[theguardian58]

Unexpected behaviour of the TOML_CFG=require_cfg_present env:

The cargo doc --open fails when TOML_CFG=require_cfg_present is set, even when there is an existing valid cfg.toml file. The cargo build, nonetheless, works as expected (i.e. fails only when the cfg.toml file is missing).

Error:

error: custom attribute panicked
  --> src\main.rs:10:1

   = help: message: TOML_CFG=require_cfg_present set, but valid config not found!

Hi @theguardian58, sorry for being so late here!

I'm not sure what is going wrong here, but I am open to suggestions on how to fix this!
