* - magic_mask specifies what features that are NOT supported by the following
* code. If a user attempts to use such a feature, parse_pathspec() can reject

*
* - flags specifies other things that the caller wants parse_pathspec to
* perform.
*
* - prefix and args come from cmd_* functions
*
* parse_pathspec() helps catch unsupported features and reject them politely.
* At a lower level, different pathspec-related functions may not support the
* same set of features. Such pathspec-sensitive functions are guarded with
* GUARD_PATHSPEC(), which will die in an unfriendly way when an unsupported
* feature is requested.
*
* The command designers are supposed to make sure that GUARD_PATHSPEC() never
* dies. They have to make sure all unsupported features are caught by
* parse_pathspec(), not by GUARD_PATHSPEC. grepping GUARD_PATHSPEC() should
* give the designers all pathspec-sensitive codepaths and what features they
* support.
*
* A similar process is applied when a new pathspec magic is added. The designer
* lifts the GUARD_PATHSPEC restriction in the functions that support the new
* magic. At the same time (s)he has to make sure this new feature will be
* caught at parse_pathspec() in commands that cannot handle the new magic in
* some cases. grepping parse_pathspec() should help.
