ConTeXt writer: deal with URL hyphenation

[bscottm]

Make ConTeXt's Link formatting aware of URL hypehnation, when it's easy to detect (i.e., when isAbsoluteURL is known to succeed or fail.)

The code looks fine on a quick perusal. (Haven't had a chance to test or look further.)

Can you say a bit about the point of this? What is the current writer getting wrong? What does the context command \hyphenatedurl do? Is it a standard part of context, or a special command that needs to be defined elsewhere in the document?

The ConTeXT writer itself isn't wrong; it needed a minor enhancement.
\hyphenatedurl does what it says it does -- hyphenates long URLs.
Otherwise, you end up with overfull hboxes and URLs running off the
edge of the page. It "pretties up" the output considerably. For
example, the following citation becomes one very large line, as
opposed to two if the URL is encapsulated within \hypenatedurl:

[2] CENDI, Frequently Asked Questions about Copyright and Computer
Software Issues Affecting the U.S. Government with Special Emphasis on
Open Source Software, 2009. [Online].
http://cendi.gov/publications/09-1FAQ_OpenSourceSoftware_FINAL_110109.pdf.

I ran into this URL hyphenation problem as the result of some hacking
on citeproc-hs, in which URLs are now passed to pandoc as Link
objects. Still waiting for Andrea to review and accept that patch.

Granted, the patch only applies to a simple and easily detectable
case. I can work on a more sophisticated patch that delves deeper into
the Link for more sophisticated cases, if you'd prefer.

Actual ConTeXT citation source:

{[}2{]} CENDI, {\em Frequently Asked Questions about Copyright and Computer Software Issues Affecting the U.S. Government with Special Emphasis on Open Source Software}, 2009. {[}Online{]}.
\useURL[urlref4][http://cendi.gov/publications/09-1FAQ_OpenSourceSoftware_FINAL_110109.pdf][][\hyphenatedurl{http://cendi.gov/publications/09-1FAQ_OpenSourceSoftware_FINAL_110109.pdf}]\from[urlref4].

Ah, I should also add that the URL is not hyphenated when characters are escaped, e.g., '_' is replaced by '\letterunderscore{}'.
