If you perform a commit, if the commit log contains a carriage return, any command located after the carriage return will not be processed.

For example, using the following commit log:
"ISSUE-1 #comment this comment
continues here #time 1d"

Only "this comment" will be added to the jira ISSUE-1 entry; #time will be completely ignored.

Carriage returns should be treated like any other characters or ignored.
In the above example:
"this comment
continues here"

should be added to ISSUE-1.
