The command

        abo sv ftp://ftp.vim.org/pub/vim/patches/7.4/README

(in a script, at a point where another buffer is displayed in a window), or even

        :view

(at the Vim command-line, when looking at that README file, to see if it has been modified), both give me

**error** (netrw) ?Invalid command.

in red (possibly Error or ErrorMsg highlight) followed on the next line by the normal

"/tmp/vHg0s9d/3" [readonly] 231L, 14146C

(or similar) in Normal highlight. The file is read into the window as if no eror had happened AFAICT. I'll try to give a little more debugging info than my usual. I don't know when it started happening but no later than 7.4.199. It still happens (as seen below) in 7.4.205. The above is from gvim (i.e. with GUI running), I've also tried to invoke "view ftp://ftp.vim.org/pub/vim/patches/7.4/README"; (without the quotes) in bash in both a konsole terminal and the no-X11 Linux console, and I get the same message.
