Yet another revision, #dos2ansi v1.6.3
https://github.com/Zirias/dos2ansi/releases/tag/v1.6.3

--- brings yet another subtle bugfix in #showansi: To set the title with an escape sequence, it uses "printf %b" with its \-notation for control characters, so literal backslashes in the title must be escaped as well 🙈

Apart from that, added nice "portability bikeshed":

- Removed the dependency on 'sed' again, quoting/escaping strings for 'eval' *can* be done in pure #POSIX #shell script.

- Added proper detection of the POSIX shell to my #zimk build system, along with variables to override the choice. Used that to generate the shebang for #dos2ansi. Really an awesome way to write /bin/sh without writing /bin/sh 😂 (rumors say there *are* POSIX systems with the compliant shell in a different path ...)

Screenshot: Yet another file with "weird" title from #SAUCE

And now there's even #dos2ansi v1.6.2: https://github.com/Zirias/dos2ansi/releases/tag/v1.6.2

The good thing is: The issues I'm fixing here are getting more and more obscure 😂

First I noticed #xterm doesn't accept all #utf8 for its '-title' option, no matter what. But it *does* support the escape sequence to set a title, so, why not use this instead.

Having added support for that (and also optionally for setting the window size using an escape sequence), I had a look at quoting again. Indeed, #showansi failed for e.g. file names containing #shell special characters.

Therefore added a *safe* quote function. The downside is, it requires #sed now. Well ....

Screenshot shows both improvements, I picked a "maximum weird" file name and used a file that has an 'ö' in its title 🥳 -- in the showansi debugging output, you can see the quoting in action 🤯
