The PR came after the 72X_pre6 deadline. I suppose it can pass as a bug-fix though it is really mostly stylistic as said (probably it is "safer" to run, I am not aware if it solves observed problems - likely not).

Tested 268e5e9 on top of CMSSW_7_2_X_2014-09-12-0200 .
No diffs observed in RECO LOCALLY (FWLite + DQM) and none expected. Note that there are some differences in jenkins, in particular in the "alternative" (DQM) comparisons - like wf 25 (known random number issue) and 4.53 (?), but not only. It looks to me the problems are only accumulating in jenkins... Any comment on the wf 4.53 issue?

It is mostly to produce good examples for my presentation at next reco meeting.
I would prefer to be in the release like this before other developers start to copy/paste

This pull request is fully signed and it will be integrated in one of the next CMSSW_7_2_X IBs unless changes (tests are also fine).
