# hooks.mailinglist
# --pretty %s", displaying the commit id, author, date and log
# message. To list full patches separated by a blank line, you
# could set this to "git show -C %s; echo".
+# To list a gitweb/cgit URL *and* a full patch for each change set, use this:
+# "t=%s; printf 'http://.../?id=%%s' \$t; echo;echo; git show -C \$t; echo"
+# Be careful if "..." contains things that will be expanded by shell "eval"
+# or printf.
+# hooks.emailmaxlines
+# The maximum number of lines that should be included in the generated
+# email body. If not specified, there is no limit.
+# Lines beyond the limit are suppressed and counted, and a final
+# line is added indicating the number of suppressed lines.
