I have tweaked LaTeX-indent-environment-list and I noticed bug#28405 [1].
Should we add gather and multline environments as well to
LaTeX-indent-environment-list like this?

diff --git a/style/amsmath.el b/style/amsmath.el
index e3cce752..d5fb1da6 100644
--- a/style/amsmath.el
+++ b/style/amsmath.el

-                       '(("equation*")
+                       '(("equation*") ("gather") ("gather*")
+                         ("gathered") ("multline") ("multline*")
                          ("align"       LaTeX-indent-tabular)
                          ("align*"      LaTeX-indent-tabular)
                          ("aligned"     LaTeX-indent-tabular)

Note that this fixes bug#28405 whereas it disables filling inside gather
and multline environments, which might confuse some users.
