autopager extension broken in Mercurial 1.9

[Yann E. MORIN]

Brodie, All,

I just upgraded to Mercurial 1.9, and noticed that the autopager
extension [0][1] is now broken.

I managed to bisect Mercurial to:

# hg up -r 1.8 && hg bisect --good
# hg up -r 1.9 && hg bisect --bad
[-- build and test, until: --]
# hg bisect --bad
The first bad revision is:
changeset:   14614:afccc64eea73
user:        Idan Kamara <idankk86 at gmail.com>
date:        Wed Jun 08 01:39:20 2011 +0300
summary:     ui: use I/O descriptors internally

I'm clueless here... :-/

I tried comparing autopager.py to pager.py, but I could not see any
meaningful difference (to me!).

Any help in solving this issue would be most welcome. :-)

Note: I'm using autopager in place of pager, because pager lacks a single
feature from autopager: handling of the prompt size. It is suggested to use
less' -F, but my prompt is 2-line high, and in case the output is strictly
one terminal high minus one line, the top-most line is eaten. And there's
no way telling 'less' about that.
