Bad match in shell completion

[williamthome]

Describe the bug
When starting an expression in the shell with begin and pressing the TAB key in a tuple after =, the shell crashes.

To Reproduce
By running erl and typing in the shell

begin {ok, Foo} = { % TAB

It crashes with the following error

*** ERROR: Shell process terminated! ***
=ERROR REPORT==== 28-Jun-2024::13:00:39.449474 ===
Error in process <0.71.0> with exit value:
{{badmatch,[]},

                 [{file,"edlin_context.erl"},{line,391}]},
  {edlin_context,over_to_opening1,2,[{file,"edlin_context.erl"},{line,339}]},
  {edlin_context,over_to_opening,1,[{file,"edlin_context.erl"},{line,328}]},

  {group,get_line1,5,[{file,"group.erl"},{line,734}]},
  {group,get_chars_loop,10,[{file,"group.erl"},{line,518}]},
  {group,io_request,6,[{file,"group.erl"},{line,213}]}]}

Expected behavior
No errors.

Affected versions
I've tested only in OTP-27.
