Template:Trim/doc

Usage
The purpose of this simple template is to trim whitespace and extra newlines from the start and end of the parameter. Example: xxxxxx gives xxxxxx

Warning
The user should get into the habit to always use the "1=", because trim will otherwise break if there is an equal sign in the input. Example: Trim breaks: Trim doesn't:  Trim breaks: Trim doesn't: The reason is that an equals sign makes the field be named. Trim will trim the first unnamed or field, but it can of course not trim the  field.
