### Implementation from FileList
---
    exclude(*patterns, &block)

---

Register a list of file name patterns that should be excluded from the
list.  Patterns may be regular expressions, glob patterns or regular
strings.  In addition, a block given to exclude will remove entries that
return true when given to the block.

Note that glob patterns are expanded against the file system. If a file
is explicitly added to a file list, but does not exist in the file
system, then an glob pattern in the exclude list will not exclude the
file.

Examples:
    FileList['a.c', 'b.c'].exclude("a.c") => ['b.c']
    FileList['a.c', 'b.c'].exclude(/^a/)  => ['b.c']

If "a.c" is a file, then ...
    FileList['a.c', 'b.c'].exclude("a.*") => ['b.c']

If "a.c" is not a file, then ...
    FileList['a.c', 'b.c'].exclude("a.*") => ['a.c', 'b.c']
