Help for user-defined functions returns just "function_name is a function" rather than appropriate help

After updating from r2018b to r2019b help for some (not all) user-defined functions returns just "<function_name> is a function" rather than appropriate help; i.e., the commented text following function definition line. Not due to name collision with other functions in the path or reserved keywords. Any ideas on how to restore expected behavior?

Turns out that this problem was related to Legacy Mac EOL encoding on the files – after converting to Unix LF encoding the help for problematic functions displayed correctly once again.
