syntax: c: require a preceding blank when a line comment contains a quote

This avoids miscolorizing part of a string when it contains a URL.

This fixes https://savannah.gnu.org/bugs/?64340.
Reported-by: Yonut Smith <deanlast3@gmail.com>

Problem has existed for more than twenty years, at least since support
for multine-line regexes was added in commit 6c1e6612 in 2002.
