Actually, for this case, tla1.1 reports "corrupt archive".

Unfortunately, I can't identify *why* the revision doesn't exist.  It
may be that the category or branch or version doesn't exist, and I don't
distinguish between those cases.  In fact, it tends to happen because I
leave out a hyphen between the category and branch

Anyone care to contribute arch_category_exists(), arch_branch_exists(),
and arch_version_exists()?

Here's a beaut I just encountered:

address@hidden tla]$ tla make-archive --listing --mirror \
address@hidden \
sftp://panoramicfeedback.com/var/www/archives/
Failure

Anyone have any idea where that comes from?  The string "Failure"
doesn't appear anywhere in /src/tla
