Dialogs 1 doesn't have documentation for the Default limitation of log messages fields

Summary

The Help for the Dialogs 1 settings screen does not mention the first field at all.

What steps will reproduce the problem?

(How one can reproduce the issue - this is very important)

1. Open TortoiseGit Settings
2. Navigate to General -> Dialogs 1
3. Click the Help button.

Alternatively, navigate to https://tortoisegit.org/docs/tortoisegit/tgit-dug-settings.html#tgit-dug-settings-dialogs and see the field not described.

What is the expected output? What do you see instead?

I'd expect an explanation of the field.

What version of TortoiseGit and Git are you using? On what operating system?

Not sure it matters as this is a documentation issue, but Windows 11, TGit 2.16.0

Please provide any additional information below, e.g. possible fixes.
