# Faster alternative to the current SVN plugin implementation.
#
# Works with svn 1.6, 1.7, 1.8.
# Use `svn_prompt_info` method to enquire the svn data.
# It's faster because his efficient use of svn (single svn call) done in the `parse_svn` function
# Also changed prompt suffix *after* the svn dirty marker
#
# *** IMPORTANT *** DO NO USE with the simple svn plugin, this plugin acts as a replacement of it.
