Incorrect counting of markdown verbatim block

When we have a file aa.md like:
```
Initial text 1

    verbatim text?

Some text \aa5
```
and a file bb.md like
```
Initial text 1

    verbatim text?
Some text \aa4
``
we get the warnings like (with current master, with 1.8.20 it is even further off):
```
aa.md:6: warning: Found unknown command '\aa5'
bb.md:5: warning: Found unknown command '\aa4'
```
instead of
```
aa.md:5: warning: Found unknown command '\aa5'
bb.md:4: warning: Found unknown command '\aa4'
```
