You can make this more legible by using '0' x40 instead of repeating
40 '0' characters. Also, it might be a good idea to support --root
directly for git-svn so the user won't have to type 40 zeroes in the
command-line :)
Sorry, I am not a perl expert or even user.
I did try to process '--root' in 'git-svn', but in vain. And I can
explain, why 40 '0'. That is the only reference to root commit as an
object that I managed to find in git - in the output of 'git-rev-list'.
If 40 '0' is not good, then it may worth to introduce a shorthand for
it, just as we have one for 'HEAD'. 'NULL' or 'ROOT' may be. If this is
implemented in 'git-rev-list', there will be no need to change 'git-svn'
at all.
