Thanks, Tony; it all makes sense now.
How about a change to :help 'langmap', so that it reads:
The 'langmap' option is a list of parts, separated with commas. Each
part can be in one of two forms:
1. A list of pairs. Each pair is a "from" character immediately
followed by the "to" character. Examples: "aA", "aAbBcC".
2. A list of "from" characters, a semi-colon and a list of "to"
characters. Example: "abc;ABC"
Special characters ';', ',', and backslash itself need to be preceded
in the option value with a backslash, meaning you must escape
backslashes twice in a |:set| command.
Example for mapping the first few alphabetic characters to their
capitalized counterpart, and also mapping '\' to I and ',' to J: >
set langmap=aA,fgh;FGH,cCdDeE,\\\\I,\\,J
