/* this program implements wildcard expansion for elvis/dos. It works
* like UNIX echo, but uses the dos wildcard conventions
* (*.* matches all files, * matches files without extension only,
* filespecs may contain drive letters, wildcards not allowed in directory
* names).
*
* It is also #included into ctags.c, ref.c, ...; in this case,
* we don't want a main function here.
