doc: gendoc.py creates valid output for option descriptions with newlines gendoc.py did not handle the hanging indentation for descriptions. Work around this by joining all in one single line (same as in minirst since previous patch). This problem occurred when translations of option lines were very long. Do not bother the translators with this detail. On a long option description, the translator continued on a new line as usual. gendoc.py created invalid rst syntax like this: -o, --option Description line 1 description line 2 The new output is: -o, --option Description line 1 description line 2 The lines could theoretically become very long, but line breaking is handled when generating the final documentation.
