the upper rule based on what you point out:
 - git-log adds 4 and 80 cols is the min directly supported
 - logs go through e-mail which wraps at 78
leaves us with user-typed paragraphs at 76

for copy & pasted output (i.e. gcc output and kernel crash logs), i
welsh on that a bit as it leaves it up to the viewer to wrap like
normal.
