[patch] get_maintainer: handle file names beginning with ./

[Dan Carpenter]

The problem is that get_maintainer.pl doesn't work if you have a ./
prefix on the filename.  For example, if you type:

    ./scripts/get_maintainer.pl -f ./drivers/usb/usb-skeleton.c

then the current code only includes LKML and people from the git log, it
doesn't include Greg or the linux-usb list.

Someone's been feeding find output to get_maintainer?

Then maybe you'd also have to consider fully qualified
file names, tilde expansion, $PWD, and probably a bunch
of other things too.

Yep.

I don't think you'd "have" to consider those as well, but I won't stand
in your way if you want to...

So strip the leading './' before using it.

Also, if you're looking for unmaintained files,
I think have a script for that too.

Half measures aren't generally good enough.

Using a combination of CWnd abs_fast_path and $lk_path
is probably better.  $lkpath is set to './' by default.

Those are fake issues though and I can't imagine how they would affect
anyone.  My issue was super annoying for me because I was sending find
output to a script and it was almost mailing the correct people because
it was using git output.  I had to debug for a long time before I
spotted the difference between ./drivers/media/radio/wl128x/fmdrv_common.c
and drivers/media/radio/wl128x/fmdrv_common.c.

I feel like I have seen this before and just manually added the correct
mailing lists back.  It's crazy annoying and easy to do.

I have no idea what this means...  It sounds like a good idea though.
:)  Please give me Reported-by credit.

Maybe this (probably won't apply because I still haven't
converted from Evolution to something that doesn't futz
up sending text emails)
