I think that's really ugly and fragile, though. And that goes for the
similar shell "feature" too.
Why ugly and fragile? grep, fgrep and egrep use the technique to good
avail, along with several other well-known utilities.
If the formail functionality is added
to procmail, it should have its own syntax, rather than look like an
external program invocation.
I wasn't suggesting that the "formail extensions" added to procmail
would rely on the `formail ...` construct. Simply pointing out that
if formail has procmail builtin than procmail may as well have
formail builtin. As in shell, a reference to a pathname with
embedded '/'s disables the optimization and invokes the full
program. By offering the ability for procmail to invoke formail
as a builtin, old scripts also run a bit faster.
