[svn] ChangeLog.README: Renamed from README.branches and added a note that Wget has

multiple ChangeLog files (currently ./ChangeLog, doc/ChangeLog, and
src/ChangeLog), since this is unusual and people have complained their patches
hadn't been applied after checking only the top-level ChangeLog.

ChangeLog.README

+Please note that Wget has more than one ChangeLog file:
+
+    ./ChangeLog: documents changes to files in the top-level directory
+                 and to files in subdirectories like po/ that don't have
+                 their own ChangeLogs 
+
+    doc/ChangeLog: documents only changes to files in the doc directory
+
+    src/ChangeLog: documents only changes to files in the src directory
+
+When checking to see if a patch you sent in has been applied, please
+look in the appropriate ChangeLog(s).
+
+In addition, you'll notice the ChangeLog-branches directories.
+
+In late 2000, time constraints delayed the release of Wget 1.6.  While
+it was awaiting release, people had new features and other changes they
+wanted added to the CVS archive, but these were deemed not safe to
+introduce just before a release.
+
+The solution was to split the stable 1.6 off onto its own branch, while
+free-wheeling development continued on the main branch (whose version
+was changed from 1.5.3+dev to 1.7-dev).
+
+Unfortunately it's difficult to portray this branched development in the
+flat ChangeLog file.  Either you include 1.6-branch changes in the
+1.7-branch ChangeLog, in which case it becomes impossible to tell what
+release version a given change first went into Wget, just judging by
+date and position in the ChangeLog, or you omit all 1.6-branch changes
+from the 1.7-branch ChangeLog, in which case all evidence of the
+existence of 1.6 (and further information about that branch) disappears
+from future versions of Wget.
+
+The solution that was decided upon was to make a subdirectory called
+ChangeLog-branches adjacent to each ChangeLog file.  Inside is the
+corresponding ChangeLog from the most recent release on the stable
+branch (e.g. 1.6_branch.ChangeLog).  This way, no information is lost
+and there's no misleading information in the ChangeLog.
