url breaking

Hi all,

a)  I've reported this before; I ca1n't seem to wrap long URLs across lines
in XeTeX

If I do this in LuaTeX it seems to work fine.

\useURL[doilink][http://dx.doi.org/10.1109/32.689404][][\hyphenatedurl{
http://dx.doi.org/10.1109/32.689404}]
\from[doilink]

But with XeTeX it insists on overflowing into the margins or into another
column.  Does anyone have a workaround?

In this latest version I don't even need the \hyphenatedurl macro :).


b)  And please, guys, will you just include a macro that will take a URL as
a parameter and typeset it.  Having to do

\useURL[doilink][http://dx.doi.org/10.1109/32.689404][][\hyphenatedurl{
http://dx.doi.org/10.1109/32.689404}]
\from[doilink]

is just unnecessary.  I'm thinking \typeurl[<url>], that's it.


c)  Is there something wrong with using \footnote{<text>} whilst in a
column?

I can send the full example off-list.  Just ping me.

Thank you,
—Mohamed

in mkiv you probably don't need the \hyphenatedurl as is more clever

in pdftex your example works ok but not in xetex ... maybe something 
messy with catcodes or discretionaries ... weird

we have this (in mkii):

\def\dohyphenatedurlbefore#1{\discretionary{\hyphenatedurlseparator}{}{}\char#1\relax}%

if you change this to

\def\dohyphenatedurlbefore#1{\discretionary{!}{?}{*}\char#1\relax}%

you'll see that indeed something is inserted

so, something fishy in xetex; maybe a difference in disc handling due to 
  utf hyphenation? anyhow, we have to live with it

(so better use mkiv)
