check-code: more replacement characters for finding '.. note::' (even) more exact by using more characters: replace '.' with 'p' and ':' with 'q'

check-code: check comment for '.. note::' without two newlines Because string entries are replaced before matching, we must search for the transformed pattern. But it seems to be quite unique and does not return false matches. If it will, they can be listed as 3rd arg in pypats.

documentation: add an extra newline after note directive Like this no docutils version interprets any line in the following text as argument of note.

tests: modify minirst test input to new format Modifying the test input data shows the effects of the last patches. In text output nothing has changed. In html output the title has moved on its own line.

minirst: do not add a 2nd empty paragraph This does not add a separating block after a separated note directive. .. note:: text is formatted to Note: text

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 fail on an empty admonition block

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.
