1259
At a minimum, a derived class must implement the log_revision method.
1261
If the LogFormatter needs to be informed of the beginning or end of
1262
a log it should implement the begin_log and/or end_log hook methods.
1264
A LogFormatter should define the following supports_XXX flags
1265
to indicate which LogRevision attributes it supports:
1267
- supports_delta must be True if this log formatter supports delta.
1268
Otherwise the delta attribute may not be populated. The 'delta_format'
1269
attribute describes whether the 'short_status' format (1) or the long
1270
one (2) should be used.
1272
- supports_merge_revisions must be True if this log formatter supports
1273
merge revisions. If not, then only mainline revisions will be passed
1276
- preferred_levels is the number of levels this formatter defaults to.
1277
The default value is zero meaning display all levels.
1278
This value is only relevant if supports_merge_revisions is True.
1280
- supports_tags must be True if this log formatter supports tags.
1281
Otherwise the tags attribute may not be populated.
1283
- supports_diff must be True if this log formatter supports diffs.
1284
Otherwise the diff attribute may not be populated.

Plugins can register functions to show custom revision properties using
1287
the properties_handler_registry. The registered function
1288
