Hi all,

Here is the update patch.

*) Remove IGNORE_BRANCHES
*) Add BRANCH_REGEXP
*) Remove '-n' from echo command line, use the original DATESTAMP format
*) Update PATH as Gerald recommend
*) Fix a typo in patch of hooks/post-commit
*) Write svn commit error messages to svn client as Gerald recommend
