MD5 digest in SpamProbe

Hi,

SpamProbe contains an optimization that skips MD5-digesting a mail when
an appropriate header (X-SpamProbe by default, see -g option) already 
exists. This
code uses a regular expression for parsing ("^[a-z]+ +[0-9]\\.[0-9]+ 
+([0-9a-z]+)").
An example header value is "GOOD 0,0005146 
17ada81378f7fdee8808e9fa492ea906".

However, the "score" command (and others) use a localized version of 
printf()
to produce this kind of string. Depending on the selected locale, the 
decimal dot
can be replaced by a comma in the output (e.g., when German locale 
"de_DE" is used),
so that the regular expression above doesn't match when the result from 
"score" is put
into the mail's header. In this case, the message is MD5-digested even 
though the header
already exists the next time it is scanned by SpamProbe.

I would suggest that either the regular expression should allow a dot or 
a comma or that
the commands produce a non-localized output (always using a decimal 
dot). This is of course
not a big issue, but might be fixed anyway.


Greetings,
Thomas.
