Thank you! I was worried about whether there could be more than one vertical 
bar preceding the file name and whether the bar could be preceded by something 
other than spaces. The answers appear to be probably not (but we need to look 
closer to be sure), and no (from looking at the GCC sources).

This means that the regexp can be further simplified and there is no need to 
make concessions for multiple vertical lines messing things up for the time 
being.
