Follow-up Comment #1, bug #39349 (project octave):

Just to clarify, the output is the transpose of the output of 


help


with no argument.  It seems that the parser is treating .' as an operator
rather than a string.  Typing


help ".'"


without brackets also works fine.

This isn't limited to "help".  Typing


ls .'


also gives the transpose of the desired string.  I'm not sure if that is for
Matlab compatibility, but I know that JWE said that some rather silly parsing
of infix operators is for Matlab compatibility, at bug #47676.


Also, help for many of the operators cannot be invoked this way, such as

help /
help '
help "


It may be worth saying that in the help text for operators, which is shown by


help .


as well as the "help NAME" text
