How would one trace history of lines 440,450 in t/t7300-clean.sh starting
from the tip of 'pu'?  "git log -p -L 440,450 pu -- t/t7300-clean.sh"
would be the most natural but it does not work (it wants "pu" to be a
path).  "git log -p -L 440,450 t/t7300-clean.sh pu" doesn't work either.

Please put the revision before the '-L' options, you can run:

git log -p origin/pu  -L 440,450 t/t7300-clean.sh

It will work.

The command line parser of this series needs to be rethought (didn't I say
that many times?  Perhaps I was ignored).  Might want to kick this out of
'next' and move to the stalled category after 1.7.3.

Yes, you have mentioned this many times, and I will put some time on this issue.

I really haven't looked at the feature, but from other commands I would
suspect:

- refs go before paths
- options go before refs

Now, if "-L x,y" is an option /specific to a single file argument/ (not
an overall option for all file arguments) it needs to go before the file
it applies to. Is it file specific?

It would still be nice to make the parser more lenient in the sense that
it accepts an "-L x,y" in the usual place and applies it to all file
arguments.
