Miscounting in markdown in case of a horizontal ruler.

When having code like:
```
A horizonal ruler by means of underscores
\aa2
____
\aa4

A horizonal ruler by means of hyphens
\bb7
- ---
\bb9

A horizonal ruler by means of asterisks
\cc12
****
\cc14
```
we get wanungs like:
```
.../aa.md:2: warning: Found unknown command '\aa2'
.../aa.md:5: warning: Found unknown command '\aa4'
.../aa.md:8: warning: Found unknown command '\bb7'
.../aa.md:11: warning: Found unknown command '\bb9'
.../aa.md:14: warning: Found unknown command '\cc12'
.../aa.md:17: warning: Found unknown command '\cc14'
```
instead of
```
.../aa.md:2: warning: Found unknown command '\aa2'
.../aa.md:4: warning: Found unknown command '\aa4'
.../aa.md:7: warning: Found unknown command '\bb7'
.../aa.md:9: warning: Found unknown command '\bb9'
.../aa.md:12: warning: Found unknown command '\cc12'
.../aa.md:14: warning: Found unknown command '\cc14'
```

This has been fixed.
