Description:
  See `help declare`:
> -l  to convert NAMEs to lower case on assignment
> -u  to convert NAMEs to upper case on assignment

Is translated in German locale to:

> -l  Konvertiert die Variabennmamen in Kleinbuchstaben.
> -u  Konvertiert die Variablennamen in Großbuchstaben.

Translating this back to English is:
> -l  Converts the name of the variable to lowercase characters.
> -u  Converts the name of the variable to uppercase characters.

Fix:

Use the following text:
> -l to convert the content of NAMEs to lowercase characters
> -l to convert the content of NAMEs to uppercase characters
