Hi,
While doing a sync up merge to my branch, I noticed some subtree
mergeinfo being recorded and decided to look into it's validity. I could
trace it back to r1054277.
In this revision, stefan2 made a copy of libsvn_diff/diff.h as
libsvn_subr/adler32.c, presumably using a 1.5.x client (x < 5) because,
this resulted in an 'empty' svn:mergeinfo property being set on the
file. I say 1.5.x where x<5 because this was fixed in 1.5.5:
<snip from CHANGES file>
...
Version 1.5.5
(22 Dec 2008, from /branches/1.5.x)
http://svn.apache.org/repos/asf/subversion/tags/1.5.5
User-visible changes:
...
* do not create mergeinfo for wc-wc moves or copies (r34184, -585))
...
</snip from CHANGES file>
This 'empty' mergeinfo has caused all future merges to record subtree
mergeinfo onto this file.
I'd like to know if it is safe to remove this mergeinfo for good.
