Perfect, it works. Thanks a lot, and to Robert and Louis too, thanks.

So basically I gather the main problem was using the /mo. Right? That
alone, with the simpler regular expression seems to do the job. (maybe
before it was running out of memory? is that what bus error means?)

However here you are using /mo instead of /m. What does the extra o
mean? And where can I read more about this topic? I've checked on the
Pragmatic Programmer book (the one online) but I can't find any info on
that.

Thanks again.
