This is due to the following patch:
commit 9e68413c7f0a7f71e1cee923ace7282d14c2e686

Fix inferior octave single-quote font lock
* lisp/progmodes/octave.el (octave-mode-syntax-table): Fix
fontification of single quotes in inferior octave mode (bug#25517).
It looks like the problem is that octave-mode-syntax-table sets single
quotes as punctuation even though GNU Octave's manual says single quotes
are string syntax [1].
[1]:
https://www.gnu.org/software/octave/doc/interpreter/String-Objects.html
And, indeed, that link says:
"A character string in Octave consists of a sequence of characters
enclosed in either double-quote or single-quote marks."
But the ' character is also a transposition operator? I don't know
Octave at all -- this seems like a rather ambiguous syntax?
