19203,Fixed a couple of function descriptions in wp-includes/plugin.php,amereservant,,"There were a couple of errors I found in the function docblocks while tinkering in the plugins.php file as well as a confusing example, so here's what I fixed:

'''add_filter()''':
It mentioned filters were for modifying ""strings"", which isn't correct since you can also use filters to modify arrays, etc., so I changed the docblock to reflect this.
I also changed the example code to {{{ var_dump($example); }}} instead of {{{ echo $example; }}} since echoing arrays/objects etc. will cause an error.

'''apply_filters()''':
The example code block was confusing since it specified a filter function, but didn't show it being added and then just called apply_filters(), which I didn't notice the relation at first.
I added the {{{add_filter()}}} function in the code example for a clearer example so the reader will better understand the usage of this function.

'''_wp_call_all_hook()''':
A mysterious '''$hook''' parameter was defined in the docblock, however the parameter simply doesn't exist.  Not sure if this was a passing thought or someone falling asleep while writing it, but I've removed it from the docblock.
