New Revision: 1150723

URL: http://svn.apache.org/viewvc?rev=1150723&view=rev
Log:
On the gpg-agent-password-store branch, send the values of the LC_CTYPE
and DISPLAY variables to gpg-agent. These might be useful for the pinentry
program.

* subversion/libsvn_auth_gpg_agent/gpg_agent.c
  (password_get_gpg_agent): If LC_CTYPE and/or DISPLAY environment variables
   are set, use their values as arguments for the --lc-ctype and --display
   options of gpg-agent.
