testsuite, cobol, modula2, rust, algol68: Extend help.exp testing and fix reported...

Last night I was surprised because make check help.exp reported the missing
dot at the end of cobol/lang.opt description below:

Wmove-index
Cobol Warning Var(move_index, 1) Init(1)
Warn if MOVE INDEX is used

but has not reported

fexec-national-charset=
Cobol Joined Var(cobol_national_charset) RejectNegative
Set the default execution character set for NATIONAL data items

a few lines earlier.

The problem is that help.exp verified output of
--help={common,optimizers,param,target,warnings} and just selected FEs:
--help={ada,c,c++,d,fortran,go} and no other languages.
Wmove-index above got reported because it appears in --help=warnings,
but fexec-national-charset= didn't, because it only appears in --help=cobol

So, the following patch adds 6 further languages to what help.exp tests
and fixes the reported bugs.
