bug#11780: 24.1.50; vc-annotate fails for files in RCS. ("cl.el" `flet' problem?)

[Richard Copley]

Assuming RCS is installed and on the path, `vc-annotate' fails (for
files under RCS).

Recipe:
SET RCSINIT=-x,v
SET TZ=Europe/London
runemacs -Q

Visit a file under RCS version control and invoke `vc-annotate'.
Result: error "Symbol's function definition is void: sw" (at
vc-rcs.el, line 1309).
