Subject: 13.1.2; \iff messes up indentation in math mode
Date: Thu, 14 Apr 2022 11:00:56 -0700

Hi there,

As the title suggests, \iff used in math mode will increase indentation
level while it is not supposed to behave like this. I have briefly
skimmed through the code and it seems to be related to the new function
LaTeX-indent-commands-regexp-make introduced in 0ce906c. The relevant
code is:

(funcall func
              LaTeX-indent-begin-list
              "if[a-zA-Z@]*\\b"
              'LaTeX-indent-begin-regexp-local)

Best,
Ruiyang

Thanks for reporting this.  Indeed, an entry if 'iff' was missing in the
function you mentioned above.  I've fixed this issue now (fa547aa71e)
which will be available with the next release.  Please don't hesitate to
report if other macros are still missing.

I'm closing this report.

Best, Arash
