Subject: [PATCH] Fix HelpCommand searching
|
|
|
|
Prevent index out of bounds exception when finding possible matches in
|
|
the help topics.
|
|
A general empty string is caught and directed to the defaultTopic by
|
|
getHelpTopic(). #findPossibleMatches hence should not concern itself
|
|
with possible empty strings anymore.
