Suddenly, without any explicit declaration of war my Vim starts to render random files in a very strange way. Actually, this should be colored and sees that weird line numbers.
I've checkout my .vimrc, but it had not changed literally for years. I've uninstalled cscope and pathogen, the only third-party extensions I have, but this steps had not lead me anywhere. The most strange thing is that sometimes I get a normal, colorized input and sometimes I don't.
I would really appreciate any hint on this issue.
