[docs] Increase verbosity for commit messages
Apparently, not everyone read the HACKING file, especially the section about commit messages. This lead to some confusion with regards to the acceptable (i.e. mandatory) format for commit messages in Clutter. Let's clarify it a little bit before I start enforcing it and reverting commits.

- When committing, use the standard git commit message format:
|
||||
|
||||
short description - MUST be less than 74 characters
|
||||
<newline> - MANDATORY empty line
|
||||
long description - Each line must be less than 80 characters

=== begin example commit ===
|
||||
Short explanation of the commit
|

|

Do NOT put the commit message on the short description line.
|
||||
One line commit messages should be avoided, unless they can be
|
||||
*fully* explained in less than 70 characters (e.g. "Fix typo in
|
||||
clutter_actor_create_pango_context() docs"). Think of the commit
|
||||
message as an email sent to the maintainers explaining "what" you
|
||||
did and, more importantly, "why" you did it. The "how" is not
|
||||
important, since "git show" will show the patch inlined with the
|
||||
commit message.
|
||||
Longer explanation explaining exactly what's changed, whether any
|
||||
external or private interfaces changed, what bugs were fixed (with bug
|
||||
tracker reference if applicable) and so forth. Be concise but not too
|
||||
brief.
|
||||
=== end example commit ===
|
||||
|
||||
Always add a brief description of the commit to the _first_ line of
|
||||
the commit and terminate by two newlines (it will work without the
|
||||
second newline, but that is not nice for the interfaces).
|
||||
|
||||
short description - MUST be less than 72 characters
|
||||
<newline> - MANDATORY empty line
|
||||
long description - Each line MUST be less than 76 characters

Do NOT put the commit message on the short description line. One line

commit messages should be avoided, unless they can be *fully* explained

in less than 72 characters (e.g. "Fix typo in

|
||||
|
||||
The brief description might optionally have a "tag", enclosed in
|
||||
square brackets, detailing what part of the repository the commit
|
||||
affected, e.g.:
|
||||
|
||||
[alpha] Add :mode property
|
||||
[text] Emit ::cursor-event only on changes
|
||||
|
||||
The tag counts as part of overall character count, so try using
|
||||
a short word.
