cvar documentation does not mention C mangling

Summary

The documentation for cvar at https://www.freepascal.org/docs-html/current/prog/progsu147.html does not mention C mangling.

Steps to reproduce

See the cvar documentation: https://www.freepascal.org/docs-html/current/prog/progsu147.html

What is the current bug behavior?

The cvar documentation states: "The cvar modifier tells the compiler that the name of the variable used in the assembler code is exactly as specified in the declaration."

What is the expected (correct) behavior?

The cvar documentation should mention that (to quote Jonas) "cvar" does not mean "do not mangle", but "mangle in the same way as the system's C compiler would".

Possible fixes

Mention C mangling.
