 """build a function to match a set of file patterns
 arguments:
 canonroot - the canonical root of the tree you're matching against
 cwd - the current working directory, if relevant
 names - patterns to find
 inc - patterns to include
 exc - patterns to exclude
-head - a regex to prepend to patterns to control whether a match is rooted
+dflt_pat - if a pattern in names has no explicit type, assume this one
+src - where these patterns came from (e.g. .hgignore)
 a pattern is one of:
-'glob:<rooted glob>'
+'glob:<glob>' - a glob relative to cwd
-'re:<rooted regexp>'
+'re:<regexp>' - a regular expression
-'path:<rooted path>'
+'path:<path>' - a path relative to canonroot
-'relglob:<relative glob>'
+'relglob:<glob>' - an unrooted glob (*.c matches C files in all dirs)
-'relpath:<relative path>'
+'relpath:<path>' - a path relative to cwd
-'relre:<relative regexp>'
+'relre:<regexp>' - a regexp that doesn't have to match the start of a name
-'<rooted path or regexp>'
+'<something>' - one of the cases above, selected by the dflt_pat argument
 returns:
 a 3-tuple containing
-- list of explicit non-pattern names passed in
+- list of roots (places where one should start a recursive walk of the fs);
+this often matches the explicit non-pattern names passed in, but also
+includes the initial part of glob: patterns that has no glob characters
 - a bool match(filename) function
 - a bool indicating if any patterns were passed in

-make head regex a rooted bool
