spacing problem

Hi

I wanted to create a completion for the following pattern:

```
app -P profileX,profileY,profileZ
```

by doing this

```
app (..... | -P <profile>[,<profile>] ...)
```

but through compleat i get

```
app -P profileX , profileY , profileZ
```

Am i doing something wrong or is it somehow possible to get rid of the spacing?
