1/ The most annoying part was the error in po/. It turns out that reading
and understanding the po/Makevars file was the key. A simple change of
variable ensures that "make dist" does not try to rebuild lyx.pot.
2/ The way tests in src/ are defined meant that the
dependency-tracking files were not all deleted. This should be OK now.

QChar codepoints are 16 bit, so it is not wise to pass blindly a
char_type value to the QChar constructor.
Use the already defined isSpace() helper tht takes care of this issue.
Related to #12519, which is only known to bite with Qt6 for now; this
bug is thus theoretical in 2.3.
The minimal vamue is set to 10%, let's set the max to 1000%. This
avoids crashes when characters are too large.
The code is refactored to be more compact and the tests are more precise.
Fixes bug #12452.

This only makes a difference in HiDpi mode.
