issues merging 4.2.x to 4.3.x

[Martin Sebor <se...@roguewave.com>]

Here's a test case that exemplifies a couple (but not all) of the
issues that I ran into while merging 4.2.x into 4.3.x and that I
don't understand.

First, the command I used to do the merge. I realize it's not quite
right (I should be merging just the diffs since the last merge but
I don't think it matter here).

   $ svn merge \
     https://svn.apache.org/repos/asf/stdcxx/branches/4.3.x/util \
     https://svn.apache.org/repos/asf/stdcxx/branches/4.2.x/util/@659252\

   U    /build/sebor/tmp/stdcxx/4.3.x/util/runall.cpp

The output lists 29 out of the 40 files in the util/ subdirectory
yet svn status on the directory reports that only one file has been
updated:

   $ svn status /build/sebor/tmp/stdcxx/4.3.x/util
   M      /build/sebor/tmp/stdcxx/4.3.x/util/path.h

Even more strange, the output of svn diff reveals that the only
difference is in the $Id$ keyword:

~$ svn diff /build/sebor/tmp/stdcxx/4.3.x/util
Index: /build/sebor/tmp/stdcxx/4.3.x/util/path.h
