20090424083317: change parseData in OldDate and IsoDate to use ByteStrings by Benedikt Schmidt <beschmi@gmail.com> Show/Hide diffThis is a performance optimization to speed up patch
parsing and make_filename. The old version used naive
list code to parse the date (drop, take, and read). Just
using the more efficient ByteString versions makes the code
fast enough to not be a bottleneck.
