rx: use is_whitespace()

Browse Source 
Wherever blanks are permissible in input, tabs ought to be permissible,
too. This is particularly relevant when -f is passed to gas (alongside
appropriate input). Also convert open-coded checks as well as ISSPACE()
uses. At the same time use is_end_of_stmt() instead of an open-coded
check in adjacent code.
