Perhaps is a dupe of bug #61521

Forgot to mention, same results with 6.4.0, 7.1.0 and tip.

"help class.method" works nicely with classdef but not well with old-style classes.

This can be tested with the Symbolic package (which uses only old-style classes for now) where "help @sym/isNone" shows the right thing but "help sym.isNone" just shows the same as "help sym".

If helpful, I can make a MWE.

- - - -

There are some other strange cases: e.g., "help sym.symvar" shows the same thing as "help symvar", it even says:

'sym.symvar' is a function from the file /home/cbm/.octavehg/share/octave/8.0.0/m/miscellaneous/symvar.m


I've been happy using "@class/method" but there are various problems with this syntax in the classdef context such as bug #48041.  But its hard to switch if one has to use different syntaxes for old-style or classdef classes (users should not need to be aware of which is which).  There is also a matlab compatibility argument for supporting the dotted notation.
