jrr6	34bd6e8bfd	feat: improve `split` error messages (#9424 ) This PR improves the error messages produced by the `split` tactic, including suggesting syntax fixes and related tactics with which it might be confused. Note that, to avoid clashing with the new error message styling conventions used in these messages, this PR also updates the formatting of the message produced by `throwTacticEx`.

Sebastian Graf	f01471f620	fix: proper "excess binders" error locations for `rintro` and `intro` (#6565 ) This PR fixes the location of the error emitted when the `rintro` and `intro` tactics cannot introduce the requested number of binders. This patch adds a few `withRef` wrappers to invocations of `MVarId.intro` to fix error locations. Perhaps `MVarId.intro` should take a syntax object to set the location itself in the future; however there are a couple other call sites which would need non-trivial fixup.

This patch adds a few `withRef` wrappers to invocations of
`MVarId.intro` to fix error locations. Perhaps `MVarId.intro` should
take a syntax object to set the location itself in the future; however
there are a couple other call sites which would need non-trivial fixup.

Closes  #5659.
