In the MIB file, comments begin with a # (pound sign) or - - (two dashes) and
continue to the end of the line.

I put my MIB file into [Wireshark]\snmp\mibs
Restart Wireshark and let him rebuild [Wireshark]\snmp\mibs\.index
But one of my MIB file are not included in the index file.

I try to remove some lines of that file, trial and error, finally I found the
problem. The following line cause this bug:
-- my comment --- 123

I do more test:
dash count   : 0 1 2 3 4 5 6 7 8 9
parse result : o o x x o o x x o o

dash count:
  how many dashes inside a comment line, ex:
  2 means: -- abcxyz -- aaaaaa
  5 means: -- abcxyz ----- aaaaaa

parse result:
  'o' means parse successfully
  'x' means parse failed
