Nice catch. Applied - funclib.sh is used by libtoolize too, so you've likely fixed a latent bug there as a bonus :) This situation came about due to a historical accident, where self tests prohibited <space><tab> by default (for obvious reasons), before we switched to sp=' '. Now that you point it out, I'm surprised it hasn't tripped us up sooner. Thanks for the patch. Cheers, -- Gary V. Vaughan (gary AT gnu DOT org)
