Package: grep
Version: 2.5.4-4
Severity: normal

It seems that whenever egrep finds something it cannot digest inside a
character class, it spews out the same error string: «Unmatched [ or [^».
This can be misleading and opens the way for long debugging time,
specially when trying to understand complex regexes. To illustrate the
point:

$ echo | egrep -v '[[:digit]]+'
egrep: Unmatched [ or [^

The brackets _are_ balanced, however the character class is not (it
lacks a finishing colon).

Thanks,

This change went into glibc when it has been synced with gnulib in
commit eb04c21373e, which is included in glibc 2.28. I am therefore
closing this bug with this version.
