+# Name of an executable or a script which returns a commit message.
+# Use this, for example, to always start a commit message with a predefined
+# prefix. Example:
+# # Extract Jira ticket number from branch name:
+# extract_ticket () {
+# if [[ "$(git rev-parse --symbolic-full-name HEAD)" =~ ([[:alpha:]]{3,}-[[:digit:]]{1,}) ]]
+# then
+# echo "\"${BASH_REMATCH[1]^^} "

+# GIT_COMPLETION_COMMIT_MESSAGE_CALLBACK=extract_ticket
+# # Doing commit:
+# git commit --message=<TAB>
+# # you would get (without the closing double quote):
+# git commit --message="ABC-1234
+#
+# You can set the following Git configuration variables to influence the behavior of
+# the completion routines:
+#
+# completion.commitMessageCallback
+#
+# Name of an executable, script or shell functions which returns a commit message.
+# See above environment variable GIT_COMPLETION_COMMIT_MESSAGE_CALLBACK.
+# The config variable gets overriden by the environment variable if latter is present.
