Quoted strings cannot start within another quoted string and end after that other string has ended. Therefore single-quoted and double-quoted strings should (as much as possible) be colorized by a single rule, so that overlapping colorations are avoided. (This also fixes a double typo in the PHP syntax (\. --> \\.) that has been there since the PHP syntax was added in 2008, commit 90ee8ee4.) This fixes https://savannah.gnu.org/bugs/?61387. Bug existed since each of these syntaxes was introduced, the oldest ones around 2006, a few others around 2015. The one that got it right was the Lua syntax from 2011.
