Comment (by daniel.kruegler@…):

 I have doubts regarding the practical usefulness of that feature (modulo
 globbing as pointed out by Beman): At least on Windows systems, path names
 are handled case-insensitive, so if you want to check whether a given path
 has a .pdf extension, you would need to check against all uppercase and
 lowercase character combinations of .pdf (.Pdf, .pDf, .pdF, ...). Note
 that this wouldn't be solved by has_extension() internally because all
 other existing lexical comparison functions of filesystem do compare
 *exactly* and for consistency reasons this function would need to do the
 same.
