i18n: fix non-matching 1st line indentations When generating documentation, indentation must match for getting the same view for translated messages. Often an output is generated anyway, but it can look different. When a syntactically wrong indentation change is done, runrst will fail (this is detected by test-gendoc.t). Fix the simple places. When translation knowledge is necessary, the entry is marked as fuzzy (and therefore skipped when generating translations). A translator can fix it later.

i18n: fix some non matching quotation marks in translations A test for this is in preparation.

i18n: do not translate rst syntax .. note:: .. note:: is rst syntax which must not be translated. Fix this in the translations. This is not the first time this happens, so there should be a note for the translator. A later patch will change the generation of the po files to write this automatically. A test in i18n/check-translation.py could help as well.
