That and we have a bunch of them, which means inserting and deleting
needs to either have a ton of options or arbitrary rules for dealing
with precedence issues, never mind permissions.

It's just generally not a good idea to have programs editing the same
files that humans do.

And frankly, I disagree that it's easier and faster to do it on the
command line unless you're a) very intimately acquainted with hg's
obscure command line options and b) not very good with editors.

Even with systems like gconf and the Windows registry, where command
line editing is possible, people almost always tweak options via the
registry editor rather than on the command line.
