Lately each time I start R, it pops up a dialog 'the svn command requires the command line developer tools ... Would you like to install the tools now?" but I don't use svn. In the Preferences -> Git / Svn panel, "enable version control" isn't enabled. If I do enable Git / svn there are input fields for their paths, but no obvious way of saying you use one not the other, or you don't have one of them installed. Anyone else see this?
