Really fix the NSC option.

For some unknown (at least to me) and weird reason even if spellchecker.php
was appended to RCUBECOMP it didn't go in the for loop:

@${ECHO} ${RCUBECOMP} # prints spellchecker.php
.for i in ${RCUBECOMP}
@{ECHO} ${i} # never prints spellchecker.php

@cd ${WRKSRC} && ${COPYTREE_SHARE} ${i} ${STAGEDIR}${WWWDIR}

.endfor
