[PATCH v2] git-svn: Print revision while searching for earliest use of path

[Deskin Miller <deskinm@umich.edu>]

When initializing a git-svn repository from a Subversion repoository,
it is common to be interested in a path which did not exist in the
initial commit to Subversion.  In a large repository, the initial fetch
may take some looking for the earliest existence of the path time while
the user receives no additional feedback.  Print the highest revision
number scanned thus far to let the user know something is still
happening.

I'd never looked closely enough at gs_fetch_loop_common to grok what was
going on, and my previous experience with svn's get_log led me to think
that git-svn would slurp up log info for all commits at once.  Silly of
me.

Eric, things are much cleaner doing as you suggest.  I added a
carriage-return at the end of the message because I like it that way,
and the line will be overwritten once it actually starts fetching data
from svn.  I don't feel strongly about it though, so if it's better to
make it a newline, please feel free to change it and apply.
