blanks in properties output
support for properties files is awesome, but output for grails properties files (I guess the are conform to java standard) unfortunately provide extra blanks between definition and content resulting something like:
default.paginate.prev = ก่อนหน้า
(notice the blanks before and after '=') where the output should be:
default.paginate.prev=ก่อนหน้า

"Each line in a .properties file normally stores a single property. Several formats are possible for each line, including key=value, key = value, key:value, and key value."
From: http://en.wikipedia.org/wiki/.properties
We used the most common practice (key = value).
