Thanks for Maarten Buis and Nick Cox for their solutions. Note to self:
persevere. I should have got those myself.
[In case you were wondering why I wanted to do this: -gllamm- has a
cluster-robust standard error option whereas -xtprobit- does not.]

What about the following solution:
*---------------------- begin example ------------------------
local coln `"bu_SA:Lfemale bu_SA:Ledq_low lnsig2u:_cons"'
local coln : subinstr local coln "lnsig2u:_cons" "pid1:_cons"
di "`coln'"
*----------------------- end example -------------------------

In the same spirit -- but assuming each name is different --
local nnames : word count `longmacro'
local last : word `nnames' of `longmacro'
local longmacro : subinstr local longmacro "`last'" "<whatever>"
