Commit af07095 extends ‘search-path-specification’ with a ‘file-type’
field, which can be 'regular.

Then, commit 7b21fe5 adds a ‘file-pattern’ field, to look for files
matching a pattern recursively.

Lastly, commit 2a8d440 uses these features for libxml2 and
$XML_CATALOG_FILES.

Comments welcome!
