[Octave-bug-tracker] [bug #50034] "help ./" causes some extraneous printout of path info

[Mike Miller]

Follow-up Comment #3, bug #50034 (project octave):

That's because "." is always in the path, and both "." and "./" are valid file
names which refer to current directory, which is in the load path.

The help function unconditionally calls which(name), which is where that first
line comes from. If which(name) prints nothing, then you get nothing, which is
what you normally see for all operators. But because which("./") prints that
it is the current directory, you get that misleading first line.

Some logic could be added to help.m to see if the given name is an operator
and not run which on it.
