ANN: regex-base version 0.72

[Chris Kuklewicz]

The version 0.71 of regex-base supplied with GHC 6.6 has a bug in
Text.Regex.Base.Context:

> instance (RegexLike a b) => RegexContext a b (MatchResult b) where

that essentially uses 'tail' where it should not, and this may even be using
tail on an empty list.  This has been patched in the just announced unstable
version of regex-base 0.83 and this message announces that the stable repository at

http://darcs.haskell.org/packages/regex-base/

now has version 0.72 which is just 0.71 with this bug fixed.

For the eventual GHC 6.6.1 release, the supplied version of regex-base should
either be conservatively updated to 0.72 or updated to the slightly more
convenient regex-unstable/regex-base version (currently 0.83).

Cheer,
