svn switch, touches files with svn:keywords

Hello subversion-users,

I think I found a bug in subversion, not in the issue tracker:

Subversion: svn, version 1.9.4 (r1740329)
   compiled Apr 24 2016, 15:40:35 on x86-microsoft-windows
System: Windows 7, SP1

Steps to reproduce:

   1. Create a branch b1.
   2. Create an dummy file in b1, with svn:keywords.
   3. Don't use the svn:keywords on the file.
   4. Commit the changes to b1.
   5. Create a branch b2, from b1.
   6. Perform a switch to b2.

Expected results:

   - Dummy file modification time hasn't change

Actual results

   - Dummy file modification time has change

This is a problem specially with header files, in C++ projects. This bug
wasn't present in svn 1.7.9 r1462340.

Can someone else confirm, and will proceed to open the issue.

Thanks,
