Subject: Case sensitivity in glob revisited

     Dir.glob( pattern, [flags] ) => array
     Dir.glob( pattern, [flags] ) {| filename | block }  => nil
------------------------------------------------------------------------
     Returns the filenames found by expanding _pattern_ which is an
     +Array+ of the patterns or the pattern +String+, either as an
     _array_ or as parameters to the block. Note that this pattern is
     not a regexp (it's closer to a shell glob). See +File::fnmatch+
for
     the meaning of the _flags_ parameter. Note that case sensitivity
     depends on your system (so +File::FNM_CASEFOLD+ is ignored)

"case sensitivity depends on your system"

Ruby's cross-platform, so Ruby should trump the system. Of course if
the system is case insensitive, to won't matter wither way. But
otherwise without this, to get case insensitivity we have to do:

  Dir.glob("[Ss][Oo][Mm][Ee][Th][Ii][Nn][Gg][Ss][Tt][Uu][Pp][Ii][Dd]")
