Hello, all According to the documentation for svn diff,
The -c M option is equivalent to -r N:M where N = M-1 The documation of the -c option agrees: this option is syntactic sugar for -r ARG-1:ARG. I tried it: svn diff -r HEAD:6876 [works] svn diff -c HEAD [fails] The -c option does not support the `HEAD' short-cut in my svn 1.12.0: E205000: Non-numeric change argument (HEAD) given to -c Did I misunderstand the documentaiton, or is it a bug?
