    7: # of this script is testing isspace/isalnum/tolower problems with the
    8: # FTS3 module.  Unfortunately, this code isn't a really principled set
    9: # of tests, because it is impossible to know where new uses of these
   10: # functions might appear.

   44: # The snippet-generation code has calls to isspace() which are sort of
   45: # hard to get to.  It finds convenient breakpoints by starting ~40
   46: # chars before and after the matched term, and scanning ~10 chars
   47: # around that position for isspace() characters.  The long word with
   48: # embedded hi-bit chars causes one of these isspace() calls to be
   49: # exercised.  The version with a couple extra spaces should cause the
   50: # other isspace() call to be exercised.  [Both cases have been tested
   51: # in the debugger, but I'm hoping to continue to catch it if simple
   52: # constant changes change things slightly.
   53: #
   54: # The trailing and leading hi-bit chars help with code which tests for
   55: # isspace() to coalesce multiple spaces.

   57: # UPDATE: The above is no longer true; there is no such code in fts3.
