An empty argument and all subsequent arguments are dropped

[bbadour]

My urfave/cli version is

v3.6.0

Checklist

• [X] Are you running the latest v3 release? ish. Issue still exists in v3.6.1
• [X] Did you check the manual for your release?
• [X] Did you perform a search about this problem?

Describe the bug

An empty arg and all subsequent arguments get dropped.

i.e. if I have a command line like the following, "" and everything following are dropped

$ command subcommand -f=something "" arg2 arg3

gets treated as

$ command subcommand -f=something

To reproduce

Any c.Run(ctx, []string{"command", "", "arg2"}) or similar will reproduce.

Observed behavior

commands with an empty argument misbehave or fail entirely.

Expected behavior

I would expect the arguments to include the empty argument and all following arguments.

Want to fix this yourself?
