[PATCH] Add support for stripping a subject prefix that's different from linkname

[Jeremy Kerr]

Hi Sascha,

Looks good. Do you think a regex would be more adaptable, or would that be 
overkill?

Could you include a change to the testsuite too? Since I'm not using the 
feature myself, I probably won't notice if I accidentally break it :)

Cheers,
