Repro steps

Have this code:

letfoo=match[1]with|_->()

You get squigglies for |, with the tip:

Possible incorrect indentation: this token is offside of context started at position (119:15). Try indenting this token further or using standard formatting conventions."

We could have an autofix to indent this correctly, yielding code:

letfoo=match[1]with|_->()

As a bonus, pressing "tab" on the second line could stop at the minimum correct indentation. Currently,
you need to press space N times to hit the exact spot.
