Remove Pharoisms to make code more portable and running on Smalltalk/X
* Use ANSI `(Character codePoint: 13)` (`10`) instead of `Character cr` (`lf`), This is more portable
and does not depend on dialects interpretation of `#cr` - Smalltalk/X convert it according to
platform line end convention (UNIX/Windows/Mac)
* Do not assume exact value of a printstring in tests, i.e., instead of
`msg includesSubstring: '$a'
code
`msg includesSubstring: $a printString.
This way, the test is independent on the printString value, which may differ among dialects.
Q: Is printString value of String and/or Character defined in ANSI?
* In assestions, instead of `#equals:` use plain old `#=`, which is more portable.
* Removed Character>>- used to create range parser. Use portable `(Interval from: $a to: $z) asParser`
instead of just `$a - $z`. Do not use ($a to: $z) asParser as in Pharo, Character>>to:
does not create an Interval but an Array (sigh).
