templates: adjust white space amount in the output of {whyunstable}
There used to be 2 spaces between divergent nodes (when not using custom
template for divergentnodes) because divergentnodes is a hybrid list, which
means it gets ' '.join()ed, but formatnode() already had a space. Now it
doesn't, which requires extra effort in writing custom templates for
whyunstable, but at least it looks correctly by default.
Test output needs to be sorted for stability.
Set vars:

Test simplemerge command:
$ cp "$CONTRIBDIR/simplemerge" .
$ echo base > base
$ echo local > local
$ cat base >> local
$ cp local orig
$ cat base > other
$ echo other >> other
changing local directly
$ $PYTHON simplemerge local base other && echo "merge succeeded"
merge succeeded
$ cat local

$ cp orig local

simplemerge [OPTS] LOCAL BASE OTHER
Simple three-way file merge utility with a minimal feature set.
Apply to LOCAL the changes necessary to go from BASE to OTHER.
By default, LOCAL is overwritten with the results of this operation.
options:
-L --label labels to use on conflict markers
-a --text treat all files as text
-p --print print results instead of overwriting LOCAL
--no-minimal no effect (DEPRECATED)
