/*

** The form of the anchor tag is determined by the g.javascriptHyperlink
** variable.  The href="URL" form is used if g.javascriptHyperlink is false.
** If g.javascriptHyperlink is true then the
** id="ID" form is used and javascript is generated in the footer to cause
** href values to be inserted after the page has loaded.  If
** g.perm.History is false, then the <a id="ID"> form is still
** generated but the javascript is not generated so the links never
** activate. 
**
** If the user lacks the Hyperlink (h) property and the "auto-hyperlink"
** setting is true, then g.perm.Hyperlink is changed from 0 to 1 and
** g.javascriptHyperlink is set to 1.  The g.javascriptHyperlink defaults
** to 0 and only changes to one if the user lacks the Hyperlink (h) property
** and the "auto-hyperlink" setting is enabled.
**
** Filling in the href="URL" using javascript is a defense against bots.
**
** The name of this routine is deliberately kept short so that can be
** easily used within @-lines.  Example:
**
**      @ %z(href("%R/artifact/%s",zUuid))%h(zFN)</a>
**
** Note %z format.  The string returned by this function is always
** obtained from fossil_malloc() so rendering it with %z will reclaim
** that memory space.
**
** There are two versions of this routine: href() does a plain hyperlink
** and xhref() adds extra attribute text.
**
** g.perm.Hyperlink is true if the user has the Hyperlink (h) property.
** Most logged in users should have this property, since we can assume
** that a logged in user is not a bot.  Only "nobody" lacks g.perm.Hyperlink,
** typically.
