I can now reproduce it and it seems that it's just a "slightly too deep" recursion when `quail-update-leim-list-file` calls `find-file-noselect` which ends up loading `vc-git` which in turn loads `diff-mode` and where the macroexpansion of some pcase macros hits the limit. I suspect (but have not been able to confirm) that it might be due to the change in `pcase--if` where we now return `(progn (ignore ,test) ,then)` instead of just `then`, which causes the macroexpansion of `pcase-let`s to be slightly more deeply nested. Then again, I had to increase max_specpdl_size from 1600 to 1740 to get past that problem, which seems like a higher impact than what I expect from this little change in `pcase--if`. In any case, rather than bump the pdl limit, I suggest the patch below, which completely avoids the need to macroexpand all that code we won't be using anyway.
