Fix the following warnings:
[SPHINX] man
../CHANGES:37: ERROR: Unexpected indentation.
../CHANGES:1183: WARNING: Block quote ends without a blank line; unexpected unindent.
./Documentation/DocConventions.rst:31: ERROR: Unexpected indentation.
./Documentation/Source-repositories.rst:2: WARNING: Duplicate explicit target name: "web access".
./Documentation/DocConventions.rst: WARNING: document isn't included in any toctree
The free format of CHANGES sometimes does not align with RST so fix it
so it's visually similar in both formats. Remove RST references to 'web
access', URLs are parsed and rendered clickable and we don't have full
reference list yet. Doc conventions have been updated to RST but not
finalized so put it to TODO section.
