Bug#682538: cdebconf-text-udeb should provide a way to disable wrapping-around

Package: cdebconf
Version: 0.171
Severity: normal


The speech synthesis in the Debian installer currently has a few issues,
which can actually be fixed the same way: dropping wrap-around.

What happens is that what speech synthesis gets is what
cdebconf-text-udeb writes to the console, for instance it would receive
the above sentence as:

"The speech synthesis currently has a few issues, which can actually
be\nfixed the same way: dropping wrap-around.\n"

And thus it considers these as two sentences. This is because in a
terminal, lines are the semantic units. This is actually also deeply
cabled in actual speech synthesizers.

Another issue is this layout:

1: Choice 1,   4: Choice 4,
2: Choice 2,   5: Choice 5,
3: Choice 3,   6: Choice 6

The speech synthesis will read "1: Choice 1, 4: Choice 4, 2: Choice 2,
5: Choice 5, 3: Choice 3, 6: Choice 6", which is far from convenient.

A solution to both problems would be to simply disable wrapping, i.e.
when some option, environment variable or debconf variable is set, make
getwidth() return e.g. 8192 (not INT_MAX, because some functions would
try to allocate that). COLUMNS would work, but it would also break
applications run from shells invoked from the main menu, so perhaps
