After opening a markdown file
```b
```
```c
int main() {}
```
markdown-load-languages will run an "evaluate-commands -itersel".
The first selection makes us run "require-module b", which fails
because that module can't be found. Since -itersel only ignores the
"no selection remaining" error we fail to run "require-module c". Fix
this by ignoring errors.
