If callable is passed, it will be called (without arguments) and
the value will be used instead.

Warning: now short for `--lines` is `-n`, not `-l`, which is taken by
`--long`.  The idea is to make it resemble `-l` in `-ls -l` (although
the real meaning for `ls` is somewhat different).

Which causes problems when our trivial loggers are used
where delay between messages cannot be predicted (e.g. testing)

htlogr::data will now sort data by keys before assembling it all into
message so that order will not differ between invocations.

Added to both Perl and Python implementations.

Not guarranteed to work back on Windows, though

Although not particularly related to development, this is very
useful for me.

Also it has it place in programming: say when I need to pick a *really
good* name for a variable but can't recall the word in EN :)
