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.
+
+ - Some versions of dash have broken variable assignment when prefixed
+ with "local", "export", and "readonly", in that the value to be
+ assigned goes through field splitting at $IFS unless quoted.
+
+ (incorrect)
+ local variable=$value
+ local variable=$(command args)
+
+ (correct)
+ local variable="$value"
+ local variable="$(command args)"

- 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.
