I never know who "we" is, but personally I went for the first option.

Hello,

after reading the doc of `align-regexp', I try to follow the example and
copy the example text

    Fred (123) 456-7890
    Alice (123) 456-7890
    Mary-Anne (123) 456-7890
    Joe (123) 456-7890

into a newly created buffer and do

M-: (align-regexp (point-min) (point-max) "\(")

I get an error:

align-region: Marker does not point anywhere

Obviously, the interactive spec modifies the entered regexp.  It's
absolutely unclear how `regexp' must look like when `align-regexp' is
called from Lisp.  We should either explain it, or say that this command
is only for interactive use.


Regards,

Michael.
