} If Zsh is compiled with dynamic loading, it is near to impossible to run
} tests without installing Zsh (at least, Zsh modules and, probably,
} functions).

I'd been noticing that.  The completion test in particular requires both
functions and dynamic loading; zregexparse needs modules.  Otherwise the
tests have been of purely builtin functionality.

Maybe we could encode this in the test-numbering scheme somehow ...

} Even setting module_path to $srcdir/Src/*(/) does not help,
} because Zsh loads modules as zsh/<module> - and we do not have zsh
} subdirectories in this case.

We can deal with that, I think.

} Of course, if any test runs as interactive, it will pick up wrong module
} anyway as we cannot override module_path at Zsh startup.

That's fixable, too.  The one thing we can't fix is that modules may be
autoloaded if the system has an /etc/zshenv file.  

} Is any module loaded at non-interactive shell startup?

Only the built-in pseudo-modules, unless /etc/zshenv causes one to be
loaded.

Here's a patch.  BTW, I noticed a number of inconsequential typos in
comptest, but didn't bother to fix any of them.  It would be nice if
comptest displayed some sort of progress indication, the way the traps
tests do; at one point while trying the changes below one of the zsh
running inside zpty exited prematurely, and the result was that comptest
locked up and had to be killed.  I didn't know how long to wait before
giving up on it.
