CodingGuidelines: describe "export VAR=VAL" rule
https://lore.kernel.org/git/201307081121.22769.tboegi@web.de/
resulted in 9968ffff (test-lint: detect 'export FOO=bar',
2013-07-08) to add a rule to t/check-non-portable-shell.pl script to
reject
export VAR=VAL
and suggest us to instead write it as two statements, i.e.,
VAR=VAL
export VAR
This however was not spelled out in the CodingGuidelines document.
We may want to re-evaluate the rule since it is from ages ago, but
for now, let's make the written rule and what the automation
enforces consistent.

hopefully nobody starts using "local" before they are reimplemented
in C ;-)
+ - Some versions of shell do not understand "export variable=value",
+ so we write "variable=value" and then "export variable" on two
+ separate lines.

- Use octal escape sequences (e.g. "\302\242"), not hexadecimal (e.g.
"\xc2\xa2") in printf format strings, since hexadecimal escape
sequences are not portable.
