Just for the archives, the script needed some more work as Bash really
hates line-breaks; if you don't want it to turn them into spaces you
need to surround it with double quotes, both when creating a variable
and when using it.

  svn_status=`svn status | egrep -iv 'path/to/ignore.me.file'`

needs to become:
  svn_status="$(svn status | egrep -iv 'path/to/ignore.me.file')"

And
  echo $svn_status | mail -c $cc -s $subject $to

needs to become:
  echo "$svn_status" | mail -c $cc -s $subject $to

I've put the updated script below.

svn_status="$(svn status | egrep -iv 'path/to/ignore.me.file')"
current_date=`date '+%d.%m.%Y'`
subject="\"SubVersion Status Report ($current_date)\""
to="blah@example.com"
cc="someone@example.com someone2@example.com"
if [ -n "$svn_status" ]
then
  echo "$svn_status" | mail -c $cc -s $subject $to
