bug bash - EOF inesperado ao procurar correspondência `"' na conclusão da guia

Eu sei que esta pergunta foi respondida muitas vezes como aqui e aqui .

Mas todos eles tinham lugares onde havia uma citação extra errônea.

Estou apenas executando um script awk simples desta forma:

awk -f test.awk -v time="$t" copy.out

Agora quando eu digito até

awk -f test.awk -v time="$t" c #Press Tab after c

E pressione tab para concluir a guia, recebo o erro:

awk -f test.awk -v time="$t" cbash: unexpected EOF while looking for matching `"'
bash: syntax error: unexpected end of file

Eu tenho o número apropriado de aspas duplas no meu comando. Eu sei disso com certeza porque se eu digitar o nome do meu arquivo sem a conclusão da guia e, em seguida, executar o comando, ele funcionará bem.

O que estou perdendo ?

Quando executo bash -xe executo as etapas acima mencionadas, recebo:

As últimas linhas dizem, unquoted $t"mas eu forneço as citações completas e funciona. Então isso não é algum tipo de bug? Quero dizer, o bash tomou a liberdade de ignorar ou analisar incorretamente minha citação inicial
