From dd2e794a214350711db46c4e08d9b19188a7d63a Mon Sep 17 00:00:00 2001 From: Thomas Rast Date: Mon, 19 Oct 2009 17:48:08 +0200 Subject: Refactor pretty_print_commit arguments into a struct pretty_print_commit() has a bunch of rarely-used arguments, and introducing more of them requires yet another update of all the call sites. Refactor most of them into a struct to make future extensions easier. The ones that stay "plain" arguments were chosen on the grounds that all callers put real arguments there, whereas some callers have 0/NULL for all arguments that were factored into the struct. We declare the struct 'const' to ensure none of the callers are bitten by the changed (no longer call-by-value) semantics.

'git commit -s' will insert a blank line before the Signed-off-by line at the end of the message, unless this last line is a Signed-off-by line itself. Common use has other trailing lines at the ends of commit text, in the style of RFC2822 headers. Be more generous in considering lines to be part of this footer. If the last paragraph of the commit message reasonably resembles RFC-2822 formatted lines, don't insert that blank line. The new Signed-off-by line is still only suppressed when the author's existing Signed-off-by is the last line of the message.

However, the logic was overzealous and missed one corner case. A message that consists of a single line that begins with Token + colon, it can be mistaken as a S-o-b's friend. We do want an empty line in such a case.
