More fallout from my issue #3765 work: I'm investing using ~/.svnrc to provide default arguments to the commandline client. In doing so, it makes loads of sense not to use the a developer's ~/.svnrc when running the tests. Since this is found via the svn_user_get_homedir() function, which uses the $HOME environment variable, we coud easily redirect that to avoid this conflict. (It would also allow testing of this feature.)
I know we provide a standard config directory in the testsuite, but wouldn't it also be reasonable to create a dummy home directory? Grepping through the python test suite yield no results for HOME, so I assume we are currently using the developer's home directory. -Hyrum
