More work on this front still to come.
Guessing that RK's issues arise when lem is run but fails, causing the script file not to get touched, but allowing addancs to run a second time. Progress with #386
Constant of that name and definition already exists in intrealTheory; the theorems showing the homomorphic connection are new to HOL.
This means that we can accurately record a dependency for the script files on the corresponding lem files and the addancs tool, but the latter will not cause a rebuild even though it will have just been rebuilt. This is the sane as what is being done inside Holmake with "heap" files. Requires HOL-Theorem-Prover/HOL@514a40b4a5 or later.
That theorem is now in listTheory under the name LENGTH_MAP2, and is also an automatic rewrite so didn't need to be quoted at all.
This theorem, along with its friend LIST_REL_SPLIT1, is now an iff rather than implication so drule fails when applied to it.

This looks to be in a loop in |

I'll look into it. |

I think/hope my fixes in HOL-Theorem-Prover/HOL@1e9e2856a1c may fix the lack of progress in |

Can test it again if you can fix the merge conflicts. |

Merges OK (as visible above), and builds up to |
Proof is now rather shorter.
