[vile] less than optimal warning from macro parser

[Clark Morgan]

1) invoke vile
2) :source the attached file (kk.txt)
3) vile complains:

    [while with no matching endwhile in 'kk.txt']

There's obviously no ~while in that macro.  I stumbled across this today
while debugging a looping macro.  During the course of a debugging
session, I removed an enclosing pair of ~while/~endwhile statements.
