TeX's algorithm is as follows.
1. Remove leading spaces in a line.
2. Remove trailing spaces in a line.
3. Condense all sequences of spaces in a line to a single spaces.
4. Convert a newline character (if not followed by another one) to
space. Exception: If the line ends with a comment character, omit
the newline character.
I think this is a clean solution, and it is the behaviour of
`texinfo.tex`. What exactly do you consider as 'wrong and
unexpected'?
