Enter your commit message in following format:
- first commit line; one line description, up to 65 chars
+ first commit line; short one line description
After one empty line, a detailed description of your changes
the description most usually spans over multiple lines.
-The 65-character (limit) seems to be common among many projects so
-that is good guideline to follow here too.
+Wrap the lines to about __72__ characters or so. On an 80 column terminal,
+if we subtract 4 columns for the indent on the left and 4 more for
+symmetry on the right, we’re left with __72__ columns.
