Shouldn't this only be used for strings? It's a bit unclear what other possibly multi-line tokens
could entail. Overall, would that be a setting for that one user?

- the code doesn't really specify which tokens could have embedded newlines; other possible options are comment and xml.
- as to the target audience: i would definitely use it in our codebase, not a big fan of ignored embedded newlines myself.

@tgodzik any additional thoughts on this?

I think I am missing the exact meaning here. whether to ignore newlines in strings
yet the newlines are outside the strings, so this only affects strings if they are inside some other srtucture?

hmm... let me add a longer explanation :)
Specifically, for PenalizeAllNewlines and SingleLineBlock policies.
The formatter frequently chooses between adding a newline and continuing the | ||
same line but either prohibiting or heavily discouraging subsequent newlines | ||
_between_ tokens, to fit the rest of the expression on the same line. | ||
|
||
However, in many cases and, for historical reasons, intentionally, newlines | ||
_within_ tokens have been frequently ignored, leading to "single-line" blocks | ||
which actually span multiple lines. | ||
|
||
This boolean parameter now allows controlling whether to ignore newlines found | ||
in syntax of strings or other possibly multi-line tokens when newlines are | ||
otherwise prohibited or undesirable (such as for single-line formatting). |

@tgodzik do you think this explanation makes it a bit clearer?

is a bit unclear to me, though I guess the example here would need to be the best explanation we can get

this is an example. contains newline but will be formatted without breaks around open and close parentheses.
Specifically, for PenalizeAllNewlines and SingleLineBlock policies. Fixes #3608.
