Good morning Gary. Yep, seems like it works when launched with,
$ vim -u NONE file.cpp
So the spf13's .vimrc seems to be conflicting somehow... Unfortunately though, it's 1100+ lines of code... Any ideas what kind of variables/commands I should investigate in the .vimrc? I'll start a bug report on Steve Francia's github (https://github.com/spf13/spf13-vim). Thanks!
