Fixing commit dates before pushing

[Tom de Vries via Gdb <gdb@sourceware.org>]

Hi,

back in 2014, a requirement was added to the contribution checklist: 
fixing commit dates ( 
https://sourceware.org/gdb/wiki/ContributionChecklist#Fixing_commit_dates ).

The related discussion is here ( 
https://inbox.sourceware.org/gdb/20140814083231.GA6283@blade.nx/T/#u ).

Looking at recent commits, this is done by a few people, but not everybody.

[ FWIW, I'm using a push script (see below) that takes care of this for 
me. ]

If not too many people actually do this, and nobody's complaining about 
it, should we drop the requirement?

Otherwise, perhaps we could invest in some pre-commit infrastructure to 
enforce/implement this more easily.

Thanks,
- Tom

$ cat ../push.sh
#!/bin/sh

set -e

branch=$(git branch \
              | grep "\*" \
              | awk '{print $2}')

echo "REMINDER: Did you apply the Approved-By/Tested-By/Reviewed-By tags?"
echo
echo "Push branch $branch upstream?"
echo "Press ^C to cancel"
