Subject: [PATCH] [svn-r11916] Purpose: Bug fix in release script

Description:
release --private should create a release without changing the current
version of the library.  This wasn't working for the libtool version, which
was getting bumped regardless.

Solution:
Fixed the release and h5vers scripts to leave the source directory
unchanged when bin/release --private is run.

Platforms tested:
mir (changes to scripts only)
