Subject: Update grammar in the Terms section of Gallina chapter Update
 doc_grammar tool

The grammar in the doc is generated semi-automatically with doc_grammar:
- the grammar is automatically extracted from the mlg files
- developer-prepared editing scripts *.mlg_edit modify the extracted
  grammar for clarity, simplicity and ordering of productions
- chunks of the resulting grammar are automatically inserted into the
  rsts using instructions embedded in the rsts

Running doc_grammar is currently a manual step.

The grammar updates in the rst files have been manually reviewed.
