bug#19505: 25.0.50; Defining a chomp function breaks electric pairing

[Tom Willemse]

The attached patch fixes the situation where a function `chomp' exists
and `electric-pair-skip-whitespace' has the value `chomp'. Since that
specific symbol is mentioned as a special case for this variable, it
seems that it shouldn't try to call a function named as such.

Basically, defining a function named `chomp' will break electric pairing
if the `electric-pair-skip-whitespace' is set to chomp.
