Tried it out a little and from the small bits I've so far it looks good. svn annotate is unfortunately a bit slow (tried it on src/program.c, takes 35 sec vs 7 sec with cvs), but I guess it can be lived with.
And why do I get this error?
kat:~/Pike/svn-test-7.7/src> svn log -r26702 program.c svn: REPORT request failed on '/repos/pike/!svn/bc/26702/Pike/7.7/src/program.c' svn: '/repos/pike/!svn/bc/26702/Pike/7.7/src/program.c' path not found
That revision has a change in that file if I look at a larger range (26000:27000), but even if no change existed I expected it to just not print anything.
