It's still a guideline, no?  (Though I admit that common sense has to
apply and there are quite often good reasons to bust the limit in
code.)  But commit messages are not code, and don't suffer from
creeping indentation that eats up half of each line, so the rationale
is not really the same.

In block text, lines near maximum length are common, but when looking at
code OTOH, long lines are usually rare, so the file is not rendered
unreadable without linewrap turned off or a bigger terminal.

For git logs, git config core.pager 'less -S' makes things a little
better I suppose, since that at least keeps the left-hand columns blank
on the commit message lines, making the log easier to skim through by
eye.  There doesn't seem to be a way to bind a key to flip line
wrapping on and off in less at runtime, though I've not dug into it.

</bikeshed>

Anyway, I was just mildly surprised, it's not a huge deal.

(Quoted: "Text-based e-mail should not exceed 80 columns per line of
text.  Consult the documentation of your e-mail client to enable proper
line breaks around column 78.".  No statement about commit messages,
and "should not exceed" is not the same as "should be wrapped to".
This document doesn't seem to consider how git formats text derived
from emails.)

Cheers
