+1, Change interface to watchdbg & grepdbg slightly so that multiple search
+ regexes are ANDed rather than ORed together. ORing is easily achieved
+ already by the usual regex pattern 'PATT..|PATT..|..' whereas ANDing could
+ not be done as easily without resorting lots of 'PATT.*PATH' things which
+ would not necessarily get what was wanted.
+2. Make sure that the pc92 C record only contains nodes and users and not
+ other extranoeus things like skimmers...
