 * The logic here for -C <dir> attempts to avoid

 * "-C /foo -C bar /file1"         does not need chdir()

 * "-C /foo -C bar /file1 file2"   needs chdir("/foo/bar") before file2

 *

 * The only correct way to handle this is to record a "pending" chdir

 * need to process a non-absolute file.  set_chdir() adds the new dir

 * to the pending list; do_chdir() actually executes any pending chdir.
