scan.l: check_escape_warning()

Hi,

could anyone please enlighten me whether this function is still needed?
AFAICT check_escape_warning() only has significant action if
warn_on_first_escape is true. This variable is set to true only on label
xqstart, but to false on xestart. However, check_escape_warning() and
check_string_escape_warning() btw. are only called in mode xe. Seems to
me that both are never called, or what am I missing?
