Yes, according to the github search documentation, ' and ) are not 
considered when searching:

You can't use the following wildcard characters as part of your search 
query: |. , : ; / \ ` ' " = * ! ? # $ & + ^ | ~ < > ( ) { } [ ]|. The 
search will simply ignore these symbols

https://help.github.com/en/articles/searching-code

I assume the search sees `(require 'cl)` simply as `require cl` and that 
can match either cl or cl-lib or other libraries that begin with cl.
