What does <fd-35> mean on Vimgolf?

开发者_运维问答

I'm trying to improve my Vim skills through VimGolf (http://www.vimgolf.com/) and I can't seem to figure out what the sequence <fd-35> means. Here's an example.

Thanks

It appears to be an artefact of the way that vimgolf is often 'played'. See this posting on the vimdev list.

In summary: golfers use

 vim -u /dev/null -N -W foo

to record their efforts. When running in an xterm or similar, vim start-up automatically tries to set some options in the terminal, and these end up rendered in the log file as a 'spurious' prefix.
