bug: exit blabla

[marimlem]

minishell:$ exit blabla
exit minishell
exit: blabla: numeric argument required
minishell:$ 

• correct error message, but should exit the shell anyways with exit code 2

[marimlem]

bash$ exit abc
exit
bash: exit: abc: numeric argument required

=> EXITS

bash$ exit abc 1
exit
bash: exit: abc: numeric argument required

=> EXITS

bash$ exit 1 2 3
exit
bash: exit: too many arguments

=> DOESN'T EXIT

[iQH4O]

fixed exit bug, exits with ec = 2 when numeric argument is required and does not exit when too many arguments, also added check for "-" for exit input, will push later with other changes on "piscine-week-fix-hao"

[marimlem]

exit 1 2 NOT OK

minishell:$ exit 1 2
exit minishell
exit: too many arguments

• exits but shouldn't
• errormessage should be: minishell: exit: too many arguments

exit abc OK

• should have minishell: in errormessage

exit a b OK

• should have minishell: in errormessage

[iQH4O]

fixed exit
