Don't know. Anyway, customization seems easier then
writing new code:

M-x customize-variable align-rules-list

C-s c-assignment

Then below you see the regexp-string, which matters.

[^-=!^&*+<>/|   
]\(\s-*[-=!^&*+<>/|]*\)=\(\s-*\)\([^=   
]\|$\)


In the middle a single, not parentised `=' - the char taken for indentation.

Simply extend expression here, replace `=' by `[{(=]' -
a group of signes. (Or any others you want indentation
work on...)

Then still two switches AFAIR.

Just below:

Set first attributes Value Menu to "Repeat:"

And again below `Bolean' to "on".

So it works for me.
