Wrong link path in IJulia

For example executing `1.x` in a Jupyter notebook gives the following error message:

```
ParseError:
# Error @ ]8;;file:///home/j/temp/In[1]#1:1\In[1]:1:1]8;;\
1.x
└┘ ── numeric constant cannot be implicitly multiplied because it ends with `.`
```

I guess here the whole `file:///home/j/smart-dispensing/julia/In[103]#1:1\In[103]` should be replaced with `In[103]`...

The rendering of the hyperlink escape sequence is a separate issue, I hope it gets supported by Jupyter: https://github.com/jupyterlab/jupyterlab/issues/15861
