* lib/gen-uni-tables.c (get_lbp): Update such that unilbrk/lbrkprop.txt comes
out as expected. Use is_property_regional_indicator.
(get_wbp): Update such that uniwbrk/wbrkprop.txt comes out as expected.
Use is_property_regional_indicator.
* lib/uniname/gen-uninames.lisp (main): Ignore empty lines and comment
lines in the aliases file. Needed because since 2015-06-20, we use the
unmodified Unicode NameAliases.txt file. Remove reference to undefined
variable. Correct indentation.
