help/templates: use hanging indent for field list Now that the field list indentation is computed automatically, we no longer need to align all fields the same. Using a simple hanging indent makes it easy to edit the text in an editor like Emacs, which will automatically recognized the hang and keep it. The fields are still output with no blank lines between them.

minirst: improve layout of field lists Before, we used the padding following the key to compute where to wrap the text. Long keys would thus give a big indentation. It also required careful alignment of the source text, making it cumbersome to items to the list. We now compute the maximum key length and use that for all items in the list. We also put a cap on the indentation: keys longer than 10 characters are put on their own line. This is similar to how rst2html handles large keys: it uses 14 as the cutoff point, but I felt that 10 was better for monospaced text in the console.

minirst: don't test regexps twice We know the regexps match since splitparagraphs used them too.

minirst: run inlineliterals too in debug mode

test-share: handle sed/GNU-sed discrepancies

Make {file_copies} usable as a --template key Before this, to display file copies in templates, you had to write something like {file_copies%filecopy}. For some reason, the {file_copy} subtemplate was used by default but not defined by default in changeset_templater, while styles were already using it. Here we define {file_copy} in changeset_templater, and change the templater to handle formatting strings like {file_copies%filecopy} with already expanded keys (in this case {file_copies}), for backward compatibility.

templatekw: change {file_copies} behaviour, add {file_copies_switch} {file_copies} template now displays file copies with or without the --copies switch being set. A new {file_copies_switch} template implements the former behaviour.
