The former shows what happens with -v which is, IIUC, how the latest
vc-svn invokes it.  The latter (empty) is what happens without -v.  I
thought I was seeing vc-svn failing to parse the verbose output with the
cryptic numbers, and mistakenly concluding that the file was not registered.

I am not seeing this 100% of the time, either.

But I just saw a related thing happening:  VC-mode accepted a commit
from me where there was no actual change in the file (the commit did not
go through to the svn repo).  Here before trying vc-next-action, I
checked svn status:

[rpgoldman-3:~/org] rpg% svn status -v todo.org
             21586    21586 rpgoldman    todo.org
[rpgoldman-3:~/org] rpg% svn status todo.org
[rpgoldman-3:~/org] rpg%

I *conjecture* that the fact that there was output from svn status is
what led vc-svn to think there was a modification and present me with
the log window to make a commit.

I confess to not understanding the innards of vc-svn that well...
