I wanted to try using bash substitution instead of sed for replacing %u and %o

But then, netfile still needs to be quoted, so

And just doing this breaks the whole vim syntax highlighting, which is
very very annoying.

I got stuck on exactly the same issue, I just spent at least one hour
on it for nothing, it really pissed me off.
Now I need sleep so I leave it to people in a more appropriate time zones to
find a solution. :) (hello Dan :D)

More seriously, I don't consider this a huge issue. The biggest issue
here in my opinion is these fucked up urls, I really hate them.
I can't stand urls that are not easy to read, write and remember, and
that cause a ton of stupid issues like this.
