Re: Moves in FSFS

On a slightly different note I noticed this oddity in lib_fs_fs/dag.c from
http://svn.apache.org/viewvc/subversion/trunk/subversion/libsvn_fs_fs/dag.c?annotate=1517479

Sure looks like a useless memory allocation from the APR pool for
copyroot_path as well as dead code rotting away quietly.

As well as this earlier in the same file:
394kfogel858545<http://svn.apache.org/viewvc/subversion/trunk/subversion/libsvn_fs_fs/dag.c?r1=858544&r2=858545&>new_noderev.copyroot_path

= parent_noderev->copyroot_rev;
397 new_noderev.copyfrom_rev = SVN_INVALID_REVNUM;398
new_noderev.copyfrom_path = NULL;

Wow, this has been here for ages... :)

Fyi,
