I've just tried the current snapshot and most (all?) of my problems
with long path names have gone away, whereas the main release was
failing at the start of the month.

Previously:

2008/03/07 20:47:05 [13024] rsync: readlink
"/AppData/Local/Application Data/Application Data/Application
Data/Application Data/Application Data/Application Data/Application
Data/A
pplication Data/Application Data/Application
Data/Adobe/Acrobat/8.0/Cache/Search80/08695a9e61055471bbeac6c64c29faa3.idx"
(in jabley) failed: File name too long (91)

But using the current snapshot, rsync (2.6.9) has been fine with the
long path names. There are some issues (hey, it's a snapshot!) which
I'll report separately, but I'm pretty happy!

Cheers,

James
