/* There are several versions of expandwildlogs(), according to the following
flags:
NODIRENT excludes all wildcards in logfile names.
Otherwise, if VMSDIRENT, MACDIRENT, WIN32DIRENT or RISCOSDIRENT is
defined, use that.
Otherwise use POSIX.2 glob, unless NOGLOB is defined when use POSIX.1
stuff, not allowing wildcards in directory names.
MACDIRENT does actually include the POSIX.1 dirent code here, but
implements all the functions itself in macstuff.c.
In all cases, expandwildlogs() takes an argument, Logfile *lp, and clones
it within the list (using clonelogs()) as it expands the wildcards. It
returns a pointer to the last clone. E.g. expandwildlogs(log2*) turns
log1 -> log2* -> log3 into log1 -> log2a -> log2b -> log3 returning log2b */
