The above happens because the default GAP workspace evidently that messes
up the help system. I think this is a bug (?), probably in GAP.
You can do the following instead:
sage: gap_console(False)
...
Or
sage: gap.SymmetricGroup? # <--- i like this

Comment:
This does fix the problem as stated, and of course the behavior with
`False` remains the same. The code makes sense, though I had to learn a
little bit about how GAP does these things and our interface.
The issue with saving... I mean, when this is called, {{{$SAGE}}} is set,
right? So I'm not sure that this is really causing any new problems.
What use case are you worried about? The `-L` isn't even called if we do
`gap_console(False)`, and if one does `True` (default) then everything is
the same as it was... I'm missing something here. Unless you think of
what the case was where this is really different from the previous
behavior, positive review.
Patchbot, apply [attachment:trac_5043-extcode-gap-console-help.patch] to
the extcode repository and [attachment:trac_5043-gap-console-help.patch]
to the Sage library.
