This may be set in the ``local variables'' section of a ChangeLog, to

A ChangeLog paragraph is a bunch of log text containing no blank lines;

a paragraph usually describes a set of changes with a single purpose,

different paragraphs are unrelated.

You could argue that the log entry for a file should contain the

full ChangeLog paragraph mentioning the change to the file, even though

it may mention other files, because that gives you the full context you

need to understand the change. This is the behaviour you get when this

variable is set to t.
|
||
|
||
On the other hand, you could argue that the log entry for a change
|

should contain only the text for the changes which occurred in that

file, because the log is per-file. This is the behaviour you get
