Description: Example: Test.IncludeAndAnchor
PmWiki correctly creates anchors, and correctly links to them. (ie
[[#sec1.2 | 1.2]])
(Honouring the syntax as defined in http://www.w3.org/TR/html4/types.html#type-name - "ID and NAME tokens must begin with a letter ([A-Za-z]) and may be followed by any number of letters, digits ([0-9]), hyphens ("-"), underscores ("_"), colons (":"), and periods (".").").
The include directive does not correctly accept anchor names with periods in them.
The problem appears to be the definition of $npat on line 1266 of pwmiki.php:
$npat = '[[:alpha:]][-\\w*]*';
Note that simply adding a dot to the [-\\w]* part of the expression won't work, as a pair of dots are used to indicate ranges. It probably needs to be something that can recognize a single dot in the identifier pattern (i.e., a dot followed by something other than another dot).
Also, I suspect the '*' immediately the \\w in the original is a typo. And there's an extraneous definition of $npat on line 1311 in the IncludeText() function, probably left over from a previous factoring of text includes.
