implemented the ^Q command for converting between line and glyph positions
* As known from DEC TECO, but extended to convert absolute positions to line numbers as well.
:^Q returns the current line.
* Especially useful in macros that accept line arguments,
as it is much shorter than something like
^E@ES/LINEFROMPOSITION//+Q.l@ES/POSITIONFROMLINE//:^E-.
* On the other hand, the fact that ^Q checks the line range means we cannot
easily replace lexer.checkheader with something like
[:J 0,^Q::S...$ ]:
Using SCI_POSITIONFROMLINE still has the advantage that it returns `Z` for out-of-bounds ranges
which would be cumbersome to write with the current ^Q.
* Perhaps there should be a separate command for converting between absolute lines and positions
and :^Q should be repurposed to return a failure boolean for out-of-range values?
* fnkeys.tes could be simplified.
