Here is a patch that implements the solution I discussed with James Baker for the automatic extraction of all MIME parts of a message with "reformime -xPREFIX".
This patch creates one more flag for reformime: "-u" so instead of "reformime -xPREFIX" I suggest "reformime -xPREFIX -u".
The -u flag will include an 8 hexa digits counter between PREFIX and the original filename.
Does anybody cares to test it?
BTW: if PREFIX is a directory, please end it with '/'. As far as I understand, this observation applies to reformime with or without this patch.
