[issue8231] Unable to run IDLE without write-access to home directory

[Terry J. Reedy]

Terry J. Reedy added the comment:

OK: call GetUserCfgDir once on creation of idleConf instance and set .userdir attribute.  Replace repeated calls in PyShell and Editor with attributes accesses.  I tested that, with patch, IDLE starts and rewrites both breakpoints.lst and recent-files.lst as appropriate.
