ⓘ Allow passing several patch URLs or files at once, e.g. webmin patch url1 url2 url3. Patches are applied in the given order, stopping at the first failure, and Webmin is reloaded only once after all of them are applied.
ⓘ GNU patch keeps a .orig copy of the original file whenever a hunk applies with fuzz or offset, which is common when patching an installed release with a commit from the master branch. Pass --no-backup-if-mismatch, since backups are not needed.
ⓘ When GNU patch is not installed, git apply was run inside the module directory, and if the Webmin root itself was a git repository, git resolved paths relative to that root and silently skipped the patched files.
Limit repository discovery to the current directory and allow reduced context, similar to the default fuzz used by patch, so slightly drifted context lines no longer cause a rejection.
