LGTM, do you think we should add any tests for this? |

I was thinking about tests. Given that we generally test in the presence of suggested packages, I guess a test of the "crayon absent" scenario will effectively be a manual test, but it won't hurt to record it officially and have an appropriate skip. |

The whole diff is covered now. I refactored the tests to use more standard testthat syntax. |

Previously
glue_col()was in some intermediate state between giving special treatment to crayon's coloring functions and not doing so. The docs (and source) strongly suggestedglue_col("{blue whatever}")would "just work" and yet that call definitely did not work.In this PR, we admit that crayon is special and simple usage of its colouring functions will now work without, e.g., attaching crayon or, in a package, importing its functions. Fancier compound styling functions, such as the concluding example of
glue_col()still require attaching or importing or the like, but I think that's (sort of) obvious. And much more rare usage, in any case.
