// Test for message: bit position '%.*s' in '%.*s' should be escaped as octal or hex [369]

/*
 * To distinguish bit positions from the description text, they should use
 * octal or hex escape sequences.  Of these, octal escape sequences are less
 * error-prone, as they consist of at most 3 octal digits, whereas hex escape
 * sequences consume as many digits as available.
