This may be an off-topic question:
I wanted to use `shortlog -s` instead of the document example,
But I found a very strange place:
Here we have two shell scripts:
$ cat ~/bin/gcount
#!/bin/sh
if test "$1" != ""
then
git log -1 --author="$1"
else
echo "hello there"
fi
cat ~/bin/gcount2
#!/bin/sh
if test "$1" != ""
then
git shortlog -1 --author="$1"
else
echo "hello there"
fi
If I use them in the terminal, there is no problem with them,
$ ~/bin/gcount gitster

The second batch
if I use .cmd to run these scripts, the situation is totally different:
$ git config -l | grep trailer
trailer.cnt.ifexists=add
trailer.cnt.key=Cnt:
trailer.cnt.cmd=~/bin/gcount
$ git interpret-trailers --trailer="cnt:gitster" <<EOF
EOF
Cnt: hello there
Cnt: commit 142430338477d9d1bb25be66267225fb58498d92

And if I turn to use gcount2:
$ git config trailer.cnt.cmd "~/bin/gcount2"
$ git interpret-trailers --trailer="cnt:gitster" <<EOF
EOF
Cnt: hello there
Cnt:
It looks like `shortlog` does not write to standard output.
Note that in `short_log.c`, log will be output to `log->file`.
Does it make the above behavior different?
Is there a good solution?
