--no--recursive option strips out "-r" line when output file is specified

[michaelusner]

When I provide the --no-recursive option to avoid pulling in all of the additional requirements, the -r <file> line is stripped out of the final file (when using the -o option).
Example:
r1.txt

-r r2.txt
aiohttp==3.9.4

r2.txt

pytest==8.2.0

Run pur with --no-recursive and --dry-run

$ pur --no-recursive --dry-run -r r1.txt
==> r1.txt <==
-r r2.txt
aiohttp==3.9.5

Note that the -r r2.txt is preserved.

Remove the --dry-run option. Note -r r2.txt is preserved:

$ pur --no-recursive -r r1.txt
Updated aiohttp: 3.9.4 -> 3.9.5
All requirements up-to-date.

$ cat r1.txt
-r r2.txt
aiohttp==3.9.5

Specify output file and note that -r r2.txt is removed:

$ pur --no-recursive -r r1.txt -o tmp
Updated aiohttp: 3.9.4 -> 3.9.5
All requirements up-to-date.

$ cat tmp
aiohttp==3.9.5

I would expect that the output file would still have the -r r2.txt preserved as both the dry run and in-place options do the same.
