Template:Trim leading/doc

Usage
Trims up to six instances of &lt;prefix&gt; (such as: 0 or "anti-") from the beginning of &lt;input&gt;. &lt;Prefix&gt; is set to "0" by default (for removing leading zeroes from numbers). Template will not properly work beyond the first whitespace in the input.

Limitations

 * Up to 100 chararacters in the input string. If possible, first check length of input string using Str len. Using strings longer than 100 characters may result in the error "max index is 100 for str_sub ".
 * Limited set of characters.
 * Snags on whitespace.
 * Expensive.
