Commented out add00.  This was here for a reason, but what?

For now we remove it, to avoid a large class of errors in which
we get 00001 instead of 1.
Fixed pattern matching of arguments in 'test-citeproc'.
Rewrite for clarity.
Util: Add trimr, triml.
Only trimr markdown output.
Added TODO comment.
Text.CSL.Eval.Output: fixed bug in toStr.

This should restore the missing spaces in suffixes and prefixes.
Minor rewrites for clarity and efficiency.
Custom Show instance for Formatting.

This makes debug output considerably less noisy.
Proc:  Fixed reversing on suffix code.
Fixed bug in chicago-author-date expected output.
Adjust entities in test-citeproc, so we don't get spurious failures.
Proc:  Manually add Space between author-in-text and rest.

The ODel element is dropped by the processing.
test-pandoc-citeproc: Temporarily switched to using html output for diffs.

This is less noisy and tells us faster what is broken.
Fixed treatment of locator_SimpleLocators.json.

Not sure if this is conceptually the best approach.
FromJSON instance for Reference:  ensure that we get spans preserved.

E.g. "nocase" information.
Fixed bug with pages in bibliographies.

Needed a change to getStringValue in Text.CSL.Eval.Common
to accommodate Formatted values.

Ultimately this is probably not the best solution.  Better etiher
to change page to a String in Reference, or to use a function that
works with a Formatted value.
Text.CSL.Proc:  Better logic for inserting Space in author-in-text.
test-citeproc:  Fixed code adjusting &#38; in expected results.
Correctly handle delimiters containing newlines.
