GNU Parallel 20150607alpha released

[Ole Tange]

GNU Parallel 20150607alpha has been released. It is available for
download at: http://alpha.gnu.org/gnu/parallel/

As always it passes the testsuite, so most functionality clearly works.

New in this release:

* An empty argument would previously cause no string to be inserted.
This is now changed to '' being inserted, thus prepending a space to
the output of: parallel echo {} b ::: ''

* --halt has been rewritten completely. You can now combine
percentages with success or fail. See the man page.

* Exit values 102..254 have been removed. 101 means more than 100 jobs failed.

* $PARALLEL_ENV can now be set to an environment prepending the
command. Used in env_parallel as mentioned in the manpage.

* --retry-failed will retry all failed jobs in a joblog. It will
ignore any command given.

* --ssh and $PARALLEL_SSH can be used to set the command used for ssh.
The command is assumed to behave the same way as ssh.

* --fifo now works in csh, too.

* Killing through --timeout, --memfree, or --halt is now done as a
process group.

* Bug fixes and man page updates.

GNU Parallel - For people who live life in the parallel lane.
