First characters seem to be their own tokens

[martpie]

Please pardon my ignorance, I'm very new to Textmate grammars.

I am working on a VS Code extension to highlight certains keys in YAML file to improve the DevX when dealing with Hydra config files (that are pure YAMLs).

While trying to select some keys, I realized the first character of each token seem to be its own token?

Example with:

array:
  - _target_: what

Notice how _ and target_ are different tokens, and how w and hat are different tokens. In this case, that make it quite hard to select _target_ as a key to apply to it a custom style.

Is that intentional? Is that some obscure part of the YAML spec I am not aware about?
