... and similar wx "variadics," which all treat wxString smartly enough that
you don't need this.
Don't need c_str either to convert wxString to const wxChar * because
wxString has a conversion operator that does the same.
Space required in path name. Also force old names that were set to temp directory to update to ones that aren't on Mac too.
Something to test on Mac -> What happens if suggested directory does not exist?
Untested on Mac (I don't have one). Might perhaps even fail to compile. But 1220 is a P1. Important enough for our schedule that we clear it now that I am happy enough to risk a 'blind patch'.
The residual issue here was that an old cfg could go on using the unsafe path. So we check for the unsafe path at init and silently substitute the good path. If the user attempts to re-instate the unsafe path we tell them no, with an informative message. This change was made more complex by windows allowing different strings for the same path, specifically C:\Users\JAMESC~1\AppData\Local\Temp\audacity_temp contains the shortening '~' so in the function that tests 'IsTempDirectoryNameOK' we use GetLongPath() to always compare the expanded names.
I also changed directory prefs to add SessionData rather than audacity_temp on the new directory name, on windows when choosing a new temp directory.
