This patch fixes comments before skipped `IfModule`, `IfDefine`, and `IfVersion` blocks being attached to the next parsed directive.
For example:
```apache
# SSL-only settings
<IfModule mod_ssl.c>
SSLEngine on
</IfModule>
ServerName example.test
```
When `mod_ssl` was unavailable, Webmin attached `# SSL-only settings` to `ServerName`. Deleting `ServerName` could then remove the wrong line and produce:
```apache
# SSL-only settings
<IfModule mod_ssl.c>
SSLEngine on
```
This fix clears comments belonging to skipped conditionals. Deleting `ServerName` now leaves the complete `IfModule` block unchanged.
