No.
However, the manual's misleading:
4. Address Groups
Usage: group [ -group name ...] { -rx expr ... | -addr expr ... }
I'd read that as: "-rx expr ..." is one of the 2 group definition
alternatives. It looks like a group is either a set of addresses or a
set of regexps.
However, the following text description then falsifies the implication:
The group command is used to directly add either addresses or
regular expressions to the specified group or groups. The
different categories of arguments to the group command can be
in any order. The flags -rx and -addr specify what the following
strings (that cannot begin with a hyphen) should be interpreted
as: either a regular expression or an email address, respectively.
That says to me you can do this:
group -group group1 -group group2 -rx regexp1 regexp2 -addr addr1 addr2 -rx
regexp3
which appends 5 definitions to "group1" and "group2". Or, on reflection,
maybe:
group -group group1 group2 -rx regexp1 regexp2 -addr addr1 addr2 -rx regexp3
On that basis I'd have written the syntax like this:
Usage: group [ -group name ]... { -rx expr... | -addr expr... }...
Note the repetition bound to each optional thing: multiple "-group name"
But the above is somewhat conjecture - we need to read the source, alas.
> - Can I group mutt aliases with -addr or just addresses?
Not sure what you mean here.
I have no -rx groups, but _all_ my mutt alias definitions take the form:
alias -group 37signals 37signals \
37signals Billing <bill...@37signals.com>, \
Jason Fried - 37signals Newsletter <newslet...@37signals.com>
which defines _both_ an alias _and_ an address based group (which have
the same name, hence the double "37signals" above - you can name these
differently).
That's because all my groups are computed from my address db.

Maybe write some index colouring rules based on the group membership?
That seems the simplest way to test this stuff to me.
I think I'm going to have to write myself a macro to "reload all my
settings" - I've had to muck around in the past trying stuff like this,
and leaving/entering mutt every time I make a change is tedious.

Looks like it should. But the regexps may need to match the whole
address part, maybe you need:
spiegl\..*@.*
Or maybe not, if they're applied to the "whole address" eg "Andy Spiegl
<mutt.a...@spiegl.de>".
I confess I'm just guessing here.
But note this in the PATTERNS section:
Special attention has to be paid when using regular expressions
inside of patterns. Specifically, Mutt's parser for these patterns
will strip one level of backslash (“\”), which is normally used for
quoting. If it is your intention to use a backslash in the regular
expression, you will need to use two backslashes instead (“\\”).
So your regexps above need backslash doubling. Or maybe quoting :-)

The source, alas.
I don't use regexps for address matching (if I can help it); they're a
lousy tool for matching addresses.
