ctest svn update no longer gathers information about changes
In CMake 3.6, a ctest_update() would correctly gather who made changes to which files. In CMake 3.7 and 3.8, that no longer works.
The LastUpdate_*.log file for 3.6 contains
--- Begin Revisions ---
"/usr/bin/svn" "log" "--xml" "-v" "-r406900:407003" "" "--non-interactive"
log-out>
...
For CMake 3.7 and 3.8, the LastUpdate_*.log file contains
--- Begin Revisions ---
"/usr/bin/svn" "log" "--xml" "-v" "-r:407003" "" "--non-interactive"
log-err> svn: E205000: Syntax error in revision argument ':407003'
