Make a release with the bugfix of the bugfix

The code in 354ef81d80 checked
for fd >= 0 but on startup the struct is memset to 0 so this
test is true. Initialize the fds to -1 to make the code work
and be able to handle all ranges of the fd.

-#   presumes this script is invoked like "./git-version-gen .tarball-version".
-
-# In order to use intra-version strings in your project, you will need two

-#
-# .tarball-version - present only in a distribution tarball, and not in

-#   be present in either $(srcdir) or $(builddir) for git-version-gen to
-#   give accurate answers during normal development with a checked out tree,
-#   but must be present in a tarball when there is no version control system.
-#   Therefore, it cannot be used in any dependencies.  GNUmakefile has
-#   hooks to force a reconfigure at distribution time to get the value
-#   correct, without penalizing normal development with extra reconfigures.

-# .version - present in a checked-out repository and in a distribution

-#   want to depend on config.h but do want to track version changes.
-#   Delete this file prior to any autoconf run where you want to rebuild
