[FIXED] possible bug %[version] IM 6.7.6.10 beta Q16

IM 6.7.6.10 beta Q16 Mac OSX Snow Leopard.

This does not seem to work as per http://www.imagemagick.org/script/escape.php:

convert xc: -format "%[version]" info:
convert: unknown image property "%[version]" @ warning/property.c/InterpretImageProperties/3225.

Already fixed and committed to SVN! Discovered it myself this morning.
Stupid program mistake.


Also fixed the %c %l producing an error instead of empty string when undefined.

Note this means that if a image has no label %l produces an empty string while %[label] produces a undefined warning (not an error that it typically fatal, but a warning.
Same goes for %c and %[comment].

This is intentional, and I have a note to update documentation about this.
