Subject: tool_urlglob: fix propagating OOM error from `sanitize_file_name()`
X-Git-Tag: curl-8_18_0~3
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=40c1748af503cf54443e17db5f537b548faa9328;p=thirdparty%2Fcurl.git

tool_urlglob: fix propagating OOM error from `sanitize_file_name()`

Make sure to convert a low-level OOM error code a libcurl one, to make
the curl tool to display an accurate error code and messages. On Windows
and MS-DOS.

Improving:
```
$ CURL_FN_SANITIZE_OOM=1 wine curl.exe https://curl.se/ --output out.txt
[...]
curl: (3) URL using bad/illegal format or missing URL
```
to:
```
[...]
curl: (27) Out of memory
```

Cherry-picked from #20116
Closes #20198
