The following provides a common structure used for Git-based commit messages.
<summary> <empty line> <description> <empty line; if meta content exists> <meta>
The summary has a suggested limit of fifty (50) characters.
Promotes small/description message.
Fits in Git shortlogs, gitk, etc.
The summary has a strenuously suggested limit of twenty-two (72) characters.
Fits with eighty (80) character terminals; considering some common usage for a four (4) character pre-fix tab for showing logs (and leaving four (4) character space at the end of each line).
The summary is suggested to be in lower case.
Clean and consistent casing for descriptions.
The summary is suggested to not end with a period.
Treat as a title.
The description has a suggested limit of twenty-two (72) characters on a single line.
Same reason as the summary; however, there are proper use cases for lines exceeding this limit. For example, complete URLs, and output dump or more.
