Details:

This is something I observed for a while, and it is bothering me. Here is how
to reproduce it:

* Type the following code into the code editor of the Octave GUI: grid on 
* Directly afterwards press the "enter" key in order to complete this line of
code and go to the next code line.
* Then unexpectedly you will have the following text in the code editor: grid
onCleanup , and you have not switched to a new line

This obviously also happens for axis on, legend on, etc. This "on" is a
speciality of the Octave/Matlab language, that I like because it makes small
scripts for data analysis and plotting easy to type.

This weired completion to "onCleanup" is a behavior of the code auto
completion inside the GUI editor. Sometimes I like what the auto completion
does, so I hesitate to generally switch it off. (There is a GUI setting to do
this). But I type things like "grid on" into my code probably 10 times per
day. And I have never ever used the Octave command "onCleanup" during my
Octave "career" that spans for significantly more than a decade now. So it
bothers me that each time when typing "grid on" I need to leave the keyboard,
and correct my code with the mouse.

I have just found that there is a setting called something like "number of
characters before opening the list of propsed commands" in the GUI editor
settings. It defaults to 2. I personally have now changed this number to 3 and
am fine myself.

But I would like to suggest that we increase the default value of this setting
from 2 to 3 as well. This way we could keep other users away from the
frustrating experience I had myself with this behavior.
