two further apparent regressions in 1.23 in s.tmac

[joerg van den hoff]

I ran into this problem several months ago but did never suspect it would be related to a preceding update to 1.23 (which happened as part of general package update run so I did not even take note until recently that groff on my machine is actually now at 1.23) so this report comes a bit late.

there are two problems.

1. major one:


2. maybe a bug, maybe a feature -- no idea:


s.tmac:stdin:15: error: must be in top-level environment, not 'nf', when first 
page is started







I do which the maintainer(s) much success, naturally.

I tried to reduce the problem to next-to-minimal but I do not know what the root issue is, so.... please try this code: attached 2 pdfs (A4 page size) formatted with groff1.22.4 and groff 1.23.0, respectively. obviously the latter one is broken (the interaction between absolute and relative .sp positioning seems to be the issue, it seems the additional '.sp 2i' is simply ignored or replace by .sp 1v in groff1.23). if you remove the first line (.LP) in the above snippet, it still formats just fine with 1.22 but fails in 1.23 with a wild guess: it has to do with virtual page break/transition onto page 1. but if so, I thought, that .DS is among the macros triggering that transition? why is the document invalid without the .LP?? for the time being I have decided to revert my installation to 1.22.4. currently there are -- for my taste, at least -- too many regressions in 1.23 (see recent threads regarding .XA and .IX, e.g.). but I of course do sincerely hope that things will stabilize/improve soon so that 1.23 (or its s.tmac, specifically) is better suited for use in "production".
