svn-create-patch could check for most obvious mistakes in patches

[Kimmo Kinnunen]

The svn-create-patch chould check for the most obvious mistakes in the patches it creates. The tool could for example warn the author for the mistakes.

A warning could be printed on at least following mistakes:
- Tabs present in the modifications
- Modifying files in a directory which would require ChangeLog entry

I don't know if it'd be useful to others, but I'll probably save following locally:

Yes, that does make sense!
