I'm not very familiar with our Lisp indentation code, I'm afraid (so
much so that I often feel like replacing it with one based on SMIE, tho
I luckily recognize it as NIH-syndrome so I managed to resist the
temptation so far).

I guess `lisp-indent-calc-next' is interpreting the "('if" as if it were
"(if"?
I must admit I have some difficulties in following the logic in that
function, perhaps Stefan has some insights here (added to CCs).

Starting Emacs with:
$ emacs -Q
I get the following indentation:
(defun word (arg)
(pcase arg
('love
'amour)
('always
'toujours)
('if
'si)
('emacs
'emacs)))
However, the indentation I expected is:
(defun word (arg)
(pcase arg
('love
'amour)
('always
'toujours)
('if
'si)
('emacs
'emacs)))
Thank you and all the best,
Markus
