in next build there will be a little change in {.set.} and {.set append.}
the value parameter will not be trimmed anymore.
i think this is a good move, because will easy the task of handling newlines.
you should rarely need to get your value trimmed, and in such cases you should handle it by using {.set|x|{.trim| yyyyy .}.}
if you find this to be a bad move, or if this will cause problems, please discuss.
