Simple string concatenation

[xkqqkx]

I could not figure out how to concatenate list of strings. For example, I would like to modify the PS1 prompt variable by prepending a string. The function join is supposed to work on lists but in my experience it won't take a list as an input. So this for some reason works (join "," "item1" "item2") but this does not (join "," (list "item1" "item2")). It would also be helpful to have a function that splits a string by white space or by a separator passed as parameter and returns a list of strings. IMHO such and similar string manipulation functions would be quite useful while being just a generalization of what's already available for path manipulations.

You're correct, there's an error in the docs. join joins parameters, not a list. apply will help here though: (apply join "," (list "item2" "item2")) will work.

I'd be open to a PR that adds string splitting.
