It's worth reiterating that it is expunging that cleans up the inbox on
the IMAP server. Compacting the local folder in SM or TB merely happens
to start off by telling the IMAP server to expunge. As such, it is
incorrect to think of it as "remove next time you compact". Expunging
happens without requiring compacting. Compacting is a LOCAL process.
Expunging is a SERVER process.

Trane, I have a POP3 email account with my ISP, and that account has a
500kB limit before it starts costing me extra money.

In my inbox, here on my computer, I have about 210 e-mails for this
year, which my file manager program (Dolphin) is telling me is 20.1MB in
size (O.K., I haven't compacted the inbox in a while (weeks))

So you're not saying that I still have all 210 e-mails sitting on my
ISP's server or, as I suspect, once I have downloaded my e-mails onto
this computer, they are (automatically) expunged from the ISP's server??
(Note: At Edit->Mail & Newsgroups Account Settings->Server
Settings->Server Settings, I have "Leave messages on Server" unchecked.)

No, I'm certainly not saying your messages are on the server. When you have leave messages unchecked, your mail spool is deleted from the server upon a successful download by a mail client. It is immediate. As I said before, expunge is an IMAP thing; it is not at all a feature of POP3 and simply does not apply.

Compacting folders, technically speaking, has nothing to do with the server, as the message stores within SeaMonkey itself are what are getting compacted. Compacting an IMAP account /does/ involve the server, however, as before the local folders can be compacted, the server spool must be expunged. After the server has expunged the inbox, SeaMonkey synchronizes the folder being compacted and ensures the detritus has been removed locally.
