I played with this for a good hour one day, and I would imagine
that others would like to see how it is done; hence the post.
You're right, there is nothing in the man page that describes
All you have to do is put the line "set modelines" in $HOME/.exrc
and put a line like "ex: set some_flags:" near the top or bottom
of the file.
A word of warning: When modelines are used, it changes the files
status to modified. This makes it a real pain to switch back and
forth between files since you have to explicitly type ":e!#"
rather than being able press <ctrl>-^.
It is also a problem when looking at source code. When you use
vi to look at a file, you have to explicitly type ":q!" to get
out of it. You can't use "ZZ" because it will cause "make" to
recompile when there is no need. I used it for a while at the
top of header files developed here with 3-space tabs. You could
turn off "warn" or map "ZZ" to ":q!", but it's too easy to have
an accident that way.
