Redundant quotes are kept while formatting a string from multiple lines to one

[yury-fedotov]

Description

Ruff formatter seems to keep redundant quotes at the edges of lines when collapsing them into one line.

P.S. Maybe it's me not using multiline strings properly, and current behavior is expected.

MRE

With line-length set at 100, running ruff format gives this diff:

- st.warning(
-     "This page is not implemented yet,"
-     " and is just a placeholder to test navigation."
- )
+ st.warning("This page is not implemented yet," " and is just a placeholder to test navigation.")

With redundant " " in the middle.

Would the lint rule ISC001 achieve what you're after here?

Good point! Let me close the issue then - I think the solution against this problem is as you stated, just use ISC001.

Ruff's formatter will join the two strings in an upcoming release early next year. See #13663
