cf1747b782 The collating sequence of the column must be TEXT if the LIKE or GLOB pattern 
starts with a "+" sign.  This is another case of ticket
[c94369cae9b561b1f996d005] that was discovered by Manuel Rigger.

83a1dafb03 When values have real affinity and are converted into strings for CHECK 
constraints or index expressions, do the conversions into a real-number format
even if the values are stored as integers for efficiency.
This appears to fix ticket [ae0f637bddc5290b446].

ticket [3182d3879020ef3b2].  There is one test case added, but most of the
tests are done in TH3.
