Zero is converted to one.
Shouldn't that be regarded a bug?
1. It is not a bug because first line has number `1', not `0'.
2. `:0read!echo "abc"' and `:1read!echo "abc"' are different, so you

punish Bram for having yet another hack for built-in commands.
You can use -range=1 to allow for a zero line number.
OK.
But a:firstline and a:lastline never become zero.
" -range=1 allows for zero range!
echo "A <line1> <line2> <count>"
com! -range=1 TestZeroRangeA echo <line1> <line2> <count>
0 TestZeroRangeA
" 0 0 0

echo "B a:firstline a:lastline"
