By the way, there is a special-case "nice" behavior that Karl and I
discussed, that we probably still need to implement in 'svn merge'.

The general form of 'svn merge' is

   'svn merge source1 source2 wc-target'

Typically, all three arguments are of the same node_kind... either all
files or dirs. If there are any mismatches, we'll most certainly get
an error. (For example, how can you diff a file and a dir? Or how
can you merge the diffs of two dirs into a file?)

But in this *one* special case, if I cd into libsvn_wc and run

   'svn merge -rX:Y update_editor.c'

Then it's obvious what I want to happen; at the moment, I'll get an
error because it's trying to merge the diffs between two files into a
default "." target. But instead, it *should* be intelligently trying
to locate the basename of the two sources within ".", and then apply
the diffs to that.

Here's a summary of behaviors in table form:

source1 source2 target behavior

fileX fileY fileZ apply diffs to fileZ
fileX fileX fileZ same.
dirA dirB dirC apply diffs within dirC
dirA dirA dirC same.

fileX fileY dir error.
dirA dirB file error.
file dir -- error.
dir file -- error.

fileX fileX dir ** try to apply diffs to dir/basename(fileX)

So the new special rule would be:

      if the sources are both the same file and wc-target is a dir,
         look for the sources' basename within target:
            apply diffs to *that*.

I'll file a bite-sized issue on this. In the meantime, people will
have to be a tad over-specific to get the behavior they want:

   'svn merge -rX:Y update_editor.c update_editor.c'

Not a showstopper or anything, just very picky. :-)
