Console: tab behaviour when pasting from clipboard

[x8x]

Could the tab autocompletion differentiate between typed TAB key and pasted text form clipboard containing tabs? If yes, tab autocompletion should probably always be turned off in such cases.

Currently, pasting this text sys(TAB)123 will return:
red>> system123
I'm not sure what would be the best solution, I think if pasting outside a string definition, tabs should be converted to spaces, so in the case above I should get:
red>> sys 123
with tab autocomplete turned off.

When pasting text containing tabs into a string definition (after an open { or an open ") tab autocompleting should be turned off and tabs converted to ^-, same treatment as CR and LF currently get.
So it would be great if after:
red>> {
pasting a string like sys(TAB)is(TAB)(LF)great} would return:
red>> {sys^-is^-^/great}

It can be dangerous!! check this example:

killme: does [q]

f: func [][
ki: 1
ki(TAB);comment
]

pasting above code in the console:

  killme: does [q]
;   func [][q]

  f: func [][
[    ki: 1
[    killme;comment
[    ]
;   func [][ki: 1 killme]

Calling the harmless 'f function! will call the could be evil 'killme function!
In this case it will luckily just quit.

Fixed by commit 7ee272a5.

Not fixed, at least not on MacOS and Linux

Yes. CLI console still has this issue.

Actually in CLI console I cannot distinguish between the text from keyboard, and the text from clipboard.
So maybe we should provide a way to disable autocompletion, something like: system/console/auto-completion?: off.

nodejs has the same issue, probably because they also can't differentiate between typed vs pasted.
In node REPL, pasting conso(TAB)//123 will print console//123
I will do some research about this.

There is a nice solution working on MacOS and Linux: "Bracketed paste mode".
Quoting: "it enables something very cool: programs can tell the difference between stuff you type manually and stuff you pasted".
Have a look https://cirw.in/blog/bracketed-paste

Please reopen this one. 8-)

@qtxie We can try that proposed solution, though it works probably only on Unix terminals, not in Windows DOS console.
