Description

svn, version 1.7.5 (r1336830)

Could error message E155021 be extended please to include the format code that 
is supported.

svn: E155021: This client is too old to work with the working copy at
'/cygdrive/c/ws/shared_ws/dev_code' (format 31).
You need to get a newer Subversion client. For more details, see
  http://subversion.apache.org/faq.html#working-copy-format-change


e.g. could it be changed to:

svn: E155021: This client supports (format 28) and is therefore too old to work 
with the working copy at '/cygdrive/c/ws/shared_ws/dev_code' (format 31).


This is useful to know, because we have various different applications which 
checkout in svn format (cygwin svn, Hudson, Jenkins, TortoiseSVN) and are 
suffering from incompatibility.

Of course, what would be even better if client formats were backwards 
compatible, and tools forward compatible. Like audio codecs are.
