Efficient way to get the previous revision number

Given a revision number I need to find out the revision of the previous
commit in a particular directory. For example, with revision 100 I
committed some change to src/dir1. Then, with revision 101 to 104 I
committed changes to src/dir2. Now, with revision 105 I committed
changes again in src/dir1. So given revision 103, and the directory
src/dir1 of course, I need to find the previous revision, i.e. 100.

What I am doing at the moment is something like

svn --quiet log [dir1 URL] 103:1 | head -2 | tail -1 | cut -d" " -f1 |
cut -dr -f2

I thought about using the --limit option but that would give me 105 (in
the example above) which is not what I'm after.

My script works just fine, but I think that getting the log from
revision 1 is a bit too much, since I just need the last one.

Does anybody think of a better, more efficient, way to achieve this?

I'm using SVN 1.4.4 and ksh for the script.

Thanks
Giulio
