Approximately 100 typo corrections spanning the whole tree, submitted via [forum:0db9827f0464bc33|forum post 0db9827f0464bc33] and individually audited and verified. Affects only code comments, innocuous test strings, error message text in tool (not library) code, and configure-level help text.

# Tests are roughly organised as follows:
#
# collate1-1.* - Single-field ORDER BY with an explicit COLLATE clause.
# collate1-2.* - Multi-field ORDER BY with an explicit COLLATE clause.
# collate1-3.* - ORDER BY using a default collation type. Also that an 
#                explicit collate type overrides a default collate type.
# collate1-4.* - ORDER BY using a data type.
#

#
# Collation type 'HEX'. If an argument can be interpreted as a hexadecimal
# number, then it is converted to one before the comparison is performed. 
# Numbers are less than other strings. If neither argument is a number, 
# [string compare] is used.
