Yes, that works if I'm logged in and working at the console, but it doesn't
solve my problem since what's happening is that I'm committing subversion
revisions over ssh and getting:

>svn ci -m c
Sending        professional/file1.txt
Sending        professional/file2.txt
Transmitting file data ..svn: Commit failed (details follow):
svn: Can't create directory

No, the ls output I gave was complete.  It's an empty directory.

Here is the full "groups" output:

webb dialout cdrom floppy audio www-data video model janet stor photo wedding
mount network music anycvs svn margi laura sbs

The group "svn" is near the end, but not 255 characters.

I found this with "linux maximum groups" with Google:

http://www-1.ibm.com/support/docview.wss?rs=984&uid=swg21207807

says 16 groups is the maximum for RPC (this is a NIS master, does that mean I'm
using RPC?) and svn is the 17th group. 

However,

http://www.linux-tutorial.info/modules.php?name=Tutorial&pageid=321

says that 32 groups is the default, but maybe that's a system limit and not
RPC limit? 

I found surprisingly few results for that search.  Is it really that uncommon
to have users that belong to more than 16 groups?  Just the Debian groups I
use for this user make 7 groups.  Not all those groups are critical, so I'll
just remove some groups, but I'm surprised at this limitation.
