--[==[
Receives a title object or string, and returns {true} if the page for the input title exists, or {false} if not.

By default, this function checks the {title.exists} key of the relevant title object, which increments the expensive function count. Normally, attempting to exceed the expensive function limit of 500 will result in an error being thrown, but this function will instead fall back to checking {title.content}, which does not increment the count. It is, however, considerably slower to check, and (unlike {title.exists}) will register as a page transclusion.

The {force_transclusion} flag may be set to force the use of transclusion ({title.content}) in all instances, which can be used to avoid incrementing the expensive function count; this is sometimes useful when making a large number of checks, as hitting the expensive function limit can be disruptive to other modules or templates.]==]

-- If it's an invalid string, return false.
