[PATCH] Subversion Command-Line Client crashes with long lists of options

From: David James <james82_at_gmail.com>

Right now, if you pass in a really long list of valid arguments into
the command-line client, you can overflow its buffer of command-line
options and execute arbitrary code. The impact of this bug is
mitigated by the fact that users who have access to the command-line
client can usually already execute arbitrary code.

To see this bug in action, type the following command:
  yes --old | head -n 300 | xargs svn

Before the patch:
   james@syntax% yes --old | head -n 300 | xargs svn
   xargs: svn: terminated by signal 11

After the patch:
  james@syntax% yes --old | head -n 300 | xargs subversion/clients/cmdline/svn
  svn: Too many options

(main): Prevent buffer overflow when list of command-line options is very long
