[Bug preprocessor/41748] New: Continued lines are not merged into one long line

["d dot g dot gorbachev at gmail dot com" <gcc-bugzilla at gcc dot gnu dot org>]

This is a testcase (a space before a backslash or after a newline, and two
pairs of quotes (or no quotes at all), are important):

"hello," \
"world"

In GCC 4.5.0 20091015, preprocessor produces this:

# 1 "<stdin>"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "<stdin>"
"hello,"
 "world"

whereas older GCC versions give this:

# 1 "<stdin>"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "<stdin>"
"hello," "world"

Such a new behavior seems to be in contradiction with what the documentation
says: "the backslash is removed and the following line is joined with the
current one."
