minirst: find admonitions before pruning comments and adding margins
Lines with only a directive are not deleted anymore because they are detected
before comments are deleted by prunecomments().
addmargins() will be adapted later.
minirst: do not interpret a directive as a literal block
When a directive was on its own line, it was interpreted as a literal block.
Example of problematic input:
.. note::
a note text
Makefile: do update on a temporary copy of a po file
This avoids having a half completed file (with a new timestamp) when msgmerge
has failed.
