Can git send-email support neomutt?

[Wu Zhenyu <wuzhenyu@xxxxxxxx>]

Excuse me.

I want to use neomutt as git send-email's cmd:

```
[sendemail]
	sendmailCmd = neomutt
```

However, I notice

```
my @sendmail_parameters = ('-i', @recipients);
...
exec ("sh", "-c", "$sendmail_cmd \"\$@\"", "-", @sendmail_parameters)
```

It call `neomutt -i to@email from@email`, which is an incorrect cmd for neomutt.

Can we customize sendmail-cmd more flexible? Like

```
[sendemail]
	sendmailCmd = neomutt %{to}
```

call `neomutt to@xxxxxxxxx`.

Thanks!
