bug#6529: --key option problem

[Victor Grishchenko]

Hi!

Today I've ran into a problem of the sort ignoring the --key parameter.
It sorts data according to the alphanumeric order of the full string instead.
Twiddling here and there (coreutils version, LC_ALL, positions, etc) did not 
work.
Any ideas?

harvest$ zcat data.log.gz | pcregrep '[TR]data' | head -10 | sort --key=17,30 
0_01_18_139_840 vtt1_100 vtt2_9#8 Tdata (0,8132)
