First off, I wrote that code, so let's not expect Ben to know what the
intention was there. :-)

No, that's not "real question." Older versions of this function asked
that question, then I determined that "is this a dir?" is the wrong
question, and "is this a wc root?" the right one. Now, if only I
could remember why...
Ah yes, reading the code helps. Further down in the function, we see:
/* Reset the schedule to normal. */
if (! wc_root)
if (modify_flags & SVN_WC__ENTRY_MODIFY_ATTRIBUTES)
/* This *should* be the removal of the .rej and .prej
remove1 = SVN_WC_ENTRY_ATTR_REJFILE;
remove2 = SVN_WC_ENTRY_ATTR_PREJFILE;
modify_flags | SVN_WC__ENTRY_MODIFY_FORCE,
This portion of code is exactly on the parent of the revert target,
which is a valid thing to do only if the revert target is not a WC
root. Why? Because by definition a WC root is either '.' (which you
really shouldn't be reverting while your inside of it) or a directory
that is disjoint with respect to its parent in the working copy,
meaning its parent has no entry for the target of the revert (and
therefore, we can't exactly update that non-existent entry).

Yeah, I'm cool wit' dat.
