Follow-up Comment #1, bug #57867 (project octave):

There are several Octave functions that operate on 2-D char arrays where
strings are normally expected.

Some of those functions, like 'strrep', may operate on the entire array and
return a result of the same size, maybe in the same shape or in a flattened

Some of those functions, like 'help', silently truncate the char array and
operate only on the first row as if it were a string.

s = ['abs'; 'def'];
help (s)

See bug #49536 for the latter type of behavior.

Are there other functions with behavior like 'strrep', so that we can
categorize these and make broader decisions? Other 'str*' functions?
