git-log produces no output

When $PAGER is set to 'less -i', we used to fail because we
assumed the $PAGER is a command and simply exec'ed it.

Try exec first, and then run it through shell if it fails. This
allows even funkier PAGERs like these ;-):

PAGER='sed -e "s/^/`date`: /" | more'
PAGER='contrib/colordiff.perl | less -RS'
