The function `calculate-lisp-indent' calls this to determine |

if the arguments of a Lisp function call should be indented specially. |

INDENT-POINT is the position at which the line being indented begins. |

Point is located at the point to indent under (for default indentation); |

STATE is the `parse-partial-sexp' state for that position. |

If the current line is in a call to a Lisp function that has a non-nil |

property `lisp-indent-function' (or the deprecated `lisp-indent-hook'), |

it specifies how to indent. The property value can be: |

* `defun', meaning indent `defun'-style |
|||
\(this is also the case if there is no property and the function |
|||
has a name that begins with \"def\", and three or more arguments); |
|||
* an integer N, meaning indent the first N arguments specially |
|||
(like ordinary function arguments), and then indent any further |
|||
arguments like a body; |
|||
* a function to call that returns the indentation (or nil). |
|||
`lisp-indent-function' calls this function with the same two arguments |
|||
that it itself received. |

This function returns either the indentation to use, or nil if the |

Lisp function does not specify a special indentation." |

Want to make the indent function of elisp aligned like this post: https://emacs.stackexchange.com/questions/10230/how-to-indent-keywords-aligned
The long answer with advice didn't work, but the code from fuco1 did. It's mit licensed; could package it up as its own package. Here it is in all its glory: https://github.com/Fuco1/.emacs.d/blob/af82072196564fa57726bdbabf97f1d35c43b7f7/site-lisp/redef.el#L20-L94
